1. Fire Safety Essentials

Objective: Equip learners with foundational knowledge of fire hazards, classes of fire, extinguisher use, and workplace prevention techniques.

Fire is a rapid chemical reaction called combustion, which produces heat, light, and flame. For fire to exist, three elements must be present:

  • Heat (a source of ignition)

  • Fuel (anything that can burn)

  • Oxygen (present in the air)

These three make up the Fire Triangle. Remove any one, and the fire goes out.

Fires are classified based on the materials fueling them. Each class requires a specific type of extinguisher. Using the wrong extinguisher on the wrong fire can be dangerous!

ClassFuel TypeExample
ASolidsWood, paper, fabric
BFlammable liquids and Flammable gasesPetrol, oil, solvents, butane, propane
CLive electrical equipment and outletsPlugged in electronics, plugged in appliances
DCombustible metalsMagnesium, sodium, Lithium
K (F)Cooking oils & fatsCommercial kitchens

When using a portable fire extinguisher:

  1. Pull the pin

  2. Aim low, at the base of the fire

  3. Squeeze the handle

  4. Sweep side to side

💡 Tip: Always stand with your back to an exit so you can escape if needed.

Prevention is better than reaction. Adopt these practices:

  • Don’t overload sockets or extension cords.

  • Keep escape routes and fire exits unobstructed.

  • Store flammable liquids in approved containers, away from heat sources.

  • Conduct routine fire drills and extinguisher inspections.

Train your team — seconds count in a fire emergency.

  • In less than 30 seconds, a small flame can turn into a major fire.

  • Over 60% of office fires start due to electrical faults.

  • Fire extinguishers must be inspected monthly and serviced annually by law in most jurisdictions.

  • Understand fire classes to apply the right response.

  • Use the PASS method when using extinguishers.

  • Fire prevention requires good housekeeping, safe storage, and routine checks.

2. PPE Compliance & Usage

Objective: Provide a clear understanding of Personal Protective Equipment (PPE), its types, proper usage, and why it is a critical line of defense in workplace safety.

Personal Protective Equipment (PPE) refers to wearable gear designed to protect workers from physical, chemical, electrical, and biological hazards when engineering or administrative controls aren't enough.

PPE does not eliminate hazards — it reduces exposure and provides last-line protection when prevention fails.

 

PPE TypePurposeExamples
Head ProtectionPrevents head trauma from impact or falling objectsHard hats, bump caps
Eye & Face ProtectionShields eyes from chemicals, debris, and radiationGoggles, face shields, safety glasses
Hearing ProtectionProtects against long-term hearing damageEarplugs, earmuffs
Respiratory ProtectionPrevents inhalation of harmful substancesDust masks, respirators, SCBA units
Hand ProtectionGuards against cuts, burns, chemicals, and infectionCut-resistant gloves, nitrile gloves
Foot ProtectionPrevents punctures, crushing, or slipsSteel-toe boots, non-slip shoes
Body ProtectionProtects from burns, chemicals, and weatherOveralls, reflective vests, lab coats
Fall ProtectionReduces risk of falls from heightSafety harnesses, lanyards
 

The right PPE depends on the risk assessment for a given task. Consider:

  • The type of hazard (chemical, noise, impact, etc.)

  • Duration and frequency of exposure

  • Fit and comfort — ill-fitting PPE can be hazardous!

💡 Tip: PPE should always be CE/ISO certified or approved by national safety standards.

  1. Inspect before each use: Look for cracks, wear, or contamination.

  2. Wear it correctly: Secure all straps and closures properly.

  3. Clean regularly: Especially face masks, goggles, and gloves.

  4. Store safely: Keep PPE in dry, clean areas away from direct sunlight or chemicals.

  5. Never share PPE unless it's thoroughly sanitized and designed for reuse.

    • A study by OSHA found that 70% of workers who suffered hand injuries were not wearing gloves.

    • Many eye injuries occur within just 5 minutes of a worker starting a task.

    • Hearing loss from noise exposure is permanent — and completely preventable.

    • PPE is your last line of defense against workplace hazards.

    • Always choose the right type of PPE based on the task.

    • Inspect, wear, clean, and store PPE properly to ensure effectiveness.

3. Workplace Safety 101

Objective: Help learners understand the core principles of workplace safety, including hazard recognition, behavioral safety, and proactive practices that prevent incidents.

Workplace safety is the process of protecting employees, equipment, and the work environment from hazards. It involves awareness, accountability, and preventive action by everyone — not just safety officers.

A safe workplace doesn't happen by luck; it’s the result of good planning, training, and behavioral discipline.

Every workplace has potential dangers. Here’s how they are typically categorized:

Hazard TypeExamples
PhysicalSlips, trips, falls, noise, poor lighting
ChemicalExposure to cleaning agents, solvents, gases
BiologicalMold, bacteria, viruses, contaminated waste
ErgonomicPoor posture, repetitive strain, awkward positions
MechanicalUnguarded machines, pinch points, sharp edges
PsychosocialStress, harassment, fatigue, burnout

Key Rule: Identifying hazards is the first step in controlling them.

 

Unsafe behaviors cause far more incidents than unsafe conditions. Here’s how to practice behavioral safety:

  • Follow procedures: Use standard operating procedures (SOPs) every time.

  • Stay alert: Fatigue or distraction leads to mistakes.

  • Use the right tool for the job: Avoid improvisation.

  • Communicate: Report hazards or near-misses immediately.

  • Lead by example: Don’t cut corners, even under pressure.

💬 Golden Principle: If it’s not safe, don’t do it — and don’t let others do it either.

Clutter and disorganization lead to injuries. Keep the workspace:

  • Clean: Remove waste promptly

  • Organized: Store tools and materials in designated places

  • Dry: Mop spills immediately

  • Clear: Maintain access to exits and fire extinguishers

Small acts like replacing lids on containers or rolling up hoses can prevent major incidents.

    • Unsafe acts — like not wearing PPE or bypassing safety features — cause 88% of workplace accidents.

    • Trip hazards (like cables or open drawers) are responsible for thousands of injuries every year.

    • A clean work area can reduce injury risk by up to 25%.

    • Workplace safety depends on awareness, behavior, and clean environments.

    • Understand different hazard types and how to manage them.

    • Practice safe habits, report hazards, and never ignore unsafe conditions.

4. First Aid Quick Tips

Objective: Equip learners with essential first aid knowledge to respond quickly and effectively to common workplace emergencies before professional help arrives.

First Aid is the immediate care given to an injured or suddenly ill person until full medical assistance is available. It aims to:

  1. Preserve life

  2. Prevent the condition from worsening

  3. Promote recovery

In a workplace, fast first aid can significantly reduce the severity of injuries and save lives.

1. Bleeding

  • Apply direct pressure with a clean cloth or bandage.

  • Elevate the wounded limb if no fracture is suspected.

  • Never remove a deeply embedded object — pad around it.

2. Burns

  • Cool the burn with running cool (not cold) water for 10–20 minutes.

  • Do not apply ice, butter, or creams.

  • Cover loosely with a non-stick, sterile dressing.

3. Fractures/Sprains

  • Do not move the injured area.

  • Immobilize the limb using a splint or support.

  • Apply cold packs to reduce swelling.

4. Choking

  • Ask if the person can cough or speak.

  • If not, perform the Heimlich maneuver (abdominal thrusts) and 5 back blows wit the heel of your palms in between their shoulder blades.

  • If unconscious, begin CPR and call emergency services.

5. CPR (Cardiopulmonary Resuscitation)

For unresponsive individuals with no breathing:

  • 30 compressions: Push hard and fast in the center of the chest.

  • 2 rescue breaths (if trained and safe to do so).

  • Repeat until help arrives or the person recovers.

📝 Always call emergency services (e.g. 112 or 767 in Nigeria) immediately in serious cases.

A well-stocked first aid kit should include at least:

  • Sterile gauze pads and bandages

  • Adhesive tape and plasters

  • Scissors and tweezers

  • Disposable gloves

  • CPR face shield or mask

  • Antiseptic wipes

  • Burn cream and ice packs

  • First aid manual

Regularly check for expiry dates and replenish used items.

The best way to stock your first aid box is to link the contents of your box to the likely risks in your site or location. 

      • Brain damage can begin within 4–6 minutes after cardiac arrest if CPR isn't started — that's why fast action matters.

      • More than 50% of workplace injuries can be treated effectively with basic first aid, reducing downtime and hospital visits.

      • Untrained bystanders often hesitate to help — but just knowing how to respond can increase victim survival dramatically.

      • Chemical burns can cause damage even after exposure ends — flushing the area immediately is critical.

      • Fainting is often caused by a sudden drop in blood pressure known as orthostatic hypotension — this reduces the force pushing blood to the brain; simply lying the person flat and raising their legs can help restore consciousness.

Other triggers of fainting include:

        • Dehydration

        • Standing up too quickly

        • Severe emotional stress

        • Vasovagal response (e.g. due to fear, pain, or seeing blood)

        • Heart problems (like arrhythmia)

      • First aid saves lives — but it must be done quickly and correctly.

      • Learn how to manage bleeding, burns, fractures, choking, and CPR.

      • Keep your first aid kit stocked, accessible, and known to all staff.

5. Environmental Awareness at Work

Objective: Empower employees to understand workplace environmental impacts and adopt sustainable practices — including waste segregation — while appreciating how these efforts contribute to broader environmental goals like those evaluated in an EIA.

Every organization has an impact on the environment. Environmental awareness helps reduce that impact by encouraging behaviors that:

  • Minimize waste and pollution

  • Use resources more efficiently

  • Comply with environmental laws

  • Improve workplace and community health

  • Support long-term sustainability goals

These actions also feed into compliance with tools like the Environmental Impact Assessment (EIA), which evaluates how business activities affect the environment before they're executed.

Even well-meaning workers can unknowingly harm the environment. Being aware of these mistakes is the first step toward creating a more eco-conscious workplace.

  1. Throwing all waste into one bin

    • Mixing recyclables, food waste, and hazardous materials contaminates everything and makes recovery difficult.

  2. Leaving lights, fans, or appliances on

    • Energy waste increases electricity bills and carbon emissions.

  3. Using excessive paper and printing everything

    • Unnecessary printing contributes to deforestation and waste.

  4. Ignoring water leaks or leaving taps running

    • A leaking tap can waste over 20 liters of water a day.

  5. Improper disposal of batteries, electronics, and chemicals

    • E-waste and chemicals can pollute soil and water when dumped carelessly.

  6. Overusing air conditioning or heating

    • This strains the energy system and contributes to climate change.

  7. Not reporting environmental hazards

    • Failing to report spills, pollution, or improper disposal allows damage to spread unnoticed.

  1. Segregate Waste at Source

    • Use clearly labeled bins: Biodegradable, Recyclables, Hazardous, and e-Waste

    • Train staff on what belongs in each bin

    • Arrange for certified disposal of hazardous and electronic waste

  2. Reduce and Reuse

    • Reuse office supplies like envelopes, folders, and cartons

    • Go digital to reduce paper consumption

  3. Conserve Energy and Water

    • Switch off lights and appliances when not in use

    • Fix leaks immediately

    • Encourage energy-efficient practices in equipment use

  4. Understand EIA Basics

    • EIA (Environmental Impact Assessment) is used to predict the effects of a project on the environment

    • It emphasizes proper waste management, pollution control, and sustainability

    • Your daily actions — like correct waste segregation — support EIA goals and compliance

      • Nigeria generates over 2.5 million tons of plastic waste annually — most of it ends up in waterways due to poor segregation.

      • A typical business can reduce 30% of its waste just by separating recyclables.

      • EIA is legally required in Nigeria for construction, oil and gas, manufacturing, and some agricultural projects.

      • Proper e-waste disposal prevents toxic substances like lead and mercury from entering soil and groundwater.

      • Environmental awareness isn’t abstract — it starts with your daily decisions.

      • Waste segregation reduces pollution and aligns with environmental best practices.

      • EIA is a key environmental tool — and your workplace practices help support its goals.

6. Lock Out, Tag Out, Try Out (LOTOTO)

Objective: To help workers understand the importance of isolating hazardous energy using the LOTOTO system, and to ensure they can safely perform maintenance by properly locking, tagging, and testing equipment before work begins.

Lock Out, Tag Out, Try Out (LOTOTO) is a critical safety system that protects workers during maintenance or servicing of machinery.
It ensures that energy sources are isolated, equipment is disabled, and most importantly — tested to verify it's safe before work begins.

Many incidents happen after LOTO (Lock out, Tag out) — because no one tried out the machine to verify it was truly de-energized.

  • Confirms all hidden or stored energy has been neutralized.

  • Catches incomplete isolation or cross-wired systems.

  • Acts as a fail-safe before a worker begins contact.

  • Required in most international best practices and audit standards.

  1. Notify affected workers of the maintenance or service activity.

  2. Shut down the equipment properly using normal procedures.

  3. Isolate energy sources — switch off breakers, close valves, etc.

  4. Lock Out the energy isolation points with physical locks.

  5. Tag Out each point with a visible warning tag stating who/why.

  6. Release stored energy (bleed, vent, drain, discharge).

  7. Try Out — attempt to restart the machine using controls to verify it's de-energized.

Try Out = Safety Check. If the machine moves or reacts, the energy wasn't fully isolated.

StepPurpose
Lock OutPhysically stops machinery from energizing
Tag OutWarns others — “Do not operate”
Try OutVerifies that the lockout is actually effective

Only authorized and trained personnel may apply or remove locks and tags.
Every individual working on the equipment should apply their own personal lock — no shared locks.

  • The "Try Out" step is missing in 1 out of 3 LOTO accidents, leading to serious injuries or fatalities.

  • Many machines have stored energy in springs, hydraulic fluid, or capacitors — even after power is cut.

  • LOTOTO isn’t just a checklist — it’s a life-saving control system that should never be skipped or rushed.

  • LOTOTO protects workers by isolating and verifying control over hazardous energy.

  • Go beyond “lock and tag” — always try out the machine to confirm it won’t start.

  • Only trained staff should perform LOTOTO.

  • Use personal locks and tags for accountability.

  • Always follow the full 7-step process — skipping any step can be fatal.

7. Electrical Safety Basics

Objective: Equip employees with practical knowledge to recognize and avoid electrical hazards in the workplace — preventing shocks, fires, and injuries.

Electricity is essential — but when misused, it becomes a serious workplace hazard. Electrical incidents can cause:

  • Shocks and electrocution

  • Burns and fires

  • Equipment damage

  • Fatal injuries and long-term disability

Most electrical accidents happen due to unsafe equipment, poor maintenance, or lack of awareness.

 

HazardExamples
Exposed wiresDamaged cords, frayed insulation
Overloaded outletsToo many appliances on a single extension
Wet conditionsOperating electrical tools with wet hands/surfaces
Faulty equipmentTools sparking, overheating, or not grounded
Improper repairsDIY fixes or untrained handling of wiring
    1. Inspect before Use

      • Always check cords, plugs, and tools for damage before using

      • Don’t use equipment with exposed wires or scorch marks

    2. Keep It Dry

      • Never use electrical devices with wet hands or near water

      • Use proper waterproof covers for outdoor equipment

    3. Don’t Overload Circuits

      • Plug only what’s necessary

      • Use power strips with surge protection

    4. Report Hazards Immediately

      • If you spot sparks, burning smells, or flickering lights — report it

      • Block off the area and label faulty equipment if needed

    5. Leave Repairs to Qualified Personnel

      • Only trained electricians should fix or open electrical panels and tools

      • Do not attempt “quick fixes” on damaged cords or machines

        • Just 50 milliamps (mA) of current — less than a household bulb — can be fatal if it passes through the heart.

        • Wet skin lowers resistance, making shock 10x more likely.

        • Most workplace electrical accidents happen with equipment rated under 240 volts — not high-voltage lines.

        • Nigeria’s safety laws require routine electrical inspections in workplaces.

        • Always check electrical equipment before use

        • Avoid wet conditions and overloaded sockets

        • Report hazards and never attempt untrained repairs

8. Food Safety & Handling Basics

Objective: Equip employees with foundational knowledge to prevent foodborne illnesses and maintain hygiene standards, especially in workplaces with catering, food storage, or communal kitchens.

Unsafe food can cause illness, lost productivity, and even reputational damage to an organization — especially in settings where food is prepared or shared.

Good food safety practices reduce the risk of contamination from bacteria, viruses, chemicals, and allergens.

    1. Maintain Personal Hygiene

      • Always wash hands before and after handling food

      • Wear clean uniforms, hairnets, and avoid jewelry

      • Cover wounds with waterproof plasters

      • Avoid handling food if you're ill (especially with vomiting or diarrhea)

    2. Keep the Kitchen & Utensils Clean

      • Sanitize surfaces, knives, boards, and equipment before and after use

      • Clean spills immediately to avoid contamination

      • Use food-safe cleaning agents

    3. Prevent Cross-Contamination

      • Store raw and cooked food separately

      • Use color-coded chopping boards and utensils

      • Never use the same gloves for raw meat and ready-to-eat foods

    4. Control Food Temperature

      • Cook meat thoroughly (e.g., chicken to at least 75°C)

      • Hot foods should stay above 60°C and cold foods below 5°C

      • Never leave cooked food at room temperature for more than 2 hours

    5. Buy and Store Food Safely

      • Buy from approved, traceable suppliers

      • Check expiry dates and packaging integrity

      • Store dry goods in clean, dry, pest-free areas

      • Label and date all food items (FIFO: First In, First Out)

  • Keep pest control records and ensure regular inspections

  • Train all staff in food safety procedures — not just cooks

  • Have a designated Food Safety Supervisor or Manager

  • Maintain temperature logs for fridges and freezers

  • Display food hygiene rules in visible staff areas

        • Over 200 diseases are caused by unsafe food handling.

        • Cross-contamination (e.g., using one knife for raw chicken and salad) is a leading cause of foodborne outbreaks.

        • Bacteria like Salmonella can double every 20 minutes in warm environments.

        • A single cockroach can carry over 30 types of bacteria, including Salmonella and E. coli.

        • Flies can contaminate food just by landing on it — transferring germs from garbage or feces.

        • Good hygiene and proper storage protect your customers and your business

        • Follow temperature rules to stop bacteria growth

        • Avoid cross-contamination at every stage of food prep

        • Always buy and store ingredients the right way

9. Emergency Response & Evacuation Awareness

Objective: Help employees understand how to respond calmly and effectively during emergencies such as fires, chemical spills, or natural disasters.

Every workplace must be prepared for sudden, dangerous situations — whether it's a fire, gas leak, injury, or chemical spill. A quick, organized response can save lives, minimize damage, and ensure business continuity.

  1. Emergency Action Plan (EAP):
    A documented plan that outlines what to do during emergencies (fire, medical, chemical, etc.). Every employee should know their role.

  2. Evacuation Routes & Assembly Points:
    Ensure escape paths are clearly marked, unobstructed, and practiced during drills. Designate safe assembly areas outside the building.

  3. Fire & Hazard Response Equipment:
    Learn the locations and correct use of:

    • Fire extinguishers

    • Fire blankets

    • Spill kits

    • First aid boxes
      Ensure regular maintenance and checks.

  4. Alarm Systems & Communication:
    Fire alarms, gas detectors, and emergency intercoms must be functional and audible across the workplace. Use clear signals and alerts.

  5. Emergency Roles & Teams:
    Assign trained personnel as:

    • Fire Wardens

    • First Aiders

    • Evacuation Coordinators
      This ensures a coordinated response during panic situations.

  6. Drills & Training:
    Conduct regular fire and emergency drills, and provide response training to both old and new staff. Practice builds calmness and confidence.

    1. Understanding the different types of emergencies that can occur at work helps tailor your response effectively. Each type has its own risks and required actions.

      Type of EmergencyExamplesBasic Response Actions
      Fire OutbreakElectrical fire, kitchen fire, warehouse blazeActivate fire alarm, evacuate, use fire extinguisher if safe, report to assembly point
      Medical EmergencyHeart attack, fainting, bleeding, seizureCall for help, provide first aid, stay calm, don't move victim unless necessary
      Chemical Spill or LeakAcid spill, gas leak, toxic fumesEvacuate area, ventilate if safe, alert emergency services, avoid direct contact
      Natural DisastersEarthquake, flood, heavy stormTake cover, shut off equipment if safe, follow evacuation orders, avoid unsafe structures
      Workplace ViolenceAggressive behavior, active threatAlert security, do not confront, stay safe or hide, notify others if possible

      Understanding the nature of the threat allows for a more focused and safe reaction — and can prevent a minor incident from becoming a major disaster.

  • In emergencies, people often freeze or panic — but trained individuals are more likely to act fast and safely.

  • According to safety studies, up to 60% of businesses never reopen after a major disaster without proper emergency planning.

  • A fire can double in size every 30 seconds — knowing how to respond quickly could prevent catastrophic loss.

  • Every workplace must have a clear Emergency Action Plan (EAP).

  • Know your evacuation routes, assembly points, and emergency contacts.

  • Familiarize yourself with emergency equipment like fire extinguishers and first aid kits.

  • Practice regular drills — they save lives when real emergencies happen.

  • Recognize the types of workplace emergencies and respond appropriately.

  • Assign and train key roles like first aiders and fire wardens.

A calm, informed response can turn chaos into control. Stay alert, stay prepared!

10. Hazard Communication (HazCom) Awareness

Objective: HazCom ensures that employees know what chemicals they’re working with, what risks those chemicals pose, and how to protect themselves.

HazCom refers to the process of identifying, labeling, and informing workers about chemical hazards in the workplace. In many countries (like the U.S.), it’s guided by OSHA’s Right-to-Know standard — every worker has the right to know about the hazardous substances they may be exposed to.

  1. Chemical Inventory List
    Every organization must keep an updated list of all hazardous chemicals present in the workplace.

  2. Safety Data Sheets (SDS)
    Formerly called MSDS, these sheets provide detailed info on each chemical’s:

    • Composition

    • Hazards

    • Handling & storage

    • Emergency procedures
      Must be readily accessible to all employees.

  3. Chemical Labels & Pictograms
    All containers must have clear labels that include:

    • Product name

    • Signal word ("Danger" or "Warning")

    • Hazard statements

    • Pictograms (like flame, skull, corrosion)

    • Precautionary statements
      These help quickly identify risks even without reading full instructions.

  4. Employee Training
    Workers must be trained on:

    • Reading SDS and labels

    • Understanding chemical hazards

    • Using PPE properly

    • First aid and emergency procedures

  5. Written HazCom Program
    Employers must have a written plan detailing how they comply with HazCom — including training, labeling, and SDS access.

Chemical / Substance (Common Use)Hazard ClassificationTarget Organ(s)Health Effects / Illnesses
Benzene (used in paints, solvents, plastics)CarcinogenBone marrow, bloodLeukemia, anemia
Asbestos (found in insulation, roofing, brake pads)CarcinogenLungsLung cancer, mesothelioma, asbestosis
Lead (used in batteries, old paints, plumbing)Neurotoxin, Reproductive ToxinBrain, kidneys, reproductive organsMemory loss, infertility, kidney damage, developmental issues
Mercury (found in thermometers, bulbs, pesticides)NeurotoxinBrain, kidneysTremors, cognitive decline, renal failure
Formaldehyde (used in plywood, resins, embalming)Carcinogen, IrritantRespiratory tract, skinAsthma, skin irritation, nasal cancer
Ammonia (common in cleaners and fertilizers)IrritantEyes, skin, respiratory systemBurns, coughing, lung irritation
Carbon Monoxide (CO) (from gas stoves, car exhausts)AsphyxiantBlood (oxygen transport inhibition)Dizziness, unconsciousness, death
Toluene (found in glue, nail polish, paint thinners)NeurotoxinBrain, liverConfusion, fatigue, liver toxicity
Pesticides (Organophosphates) (used in agriculture)Neurotoxin, Cholinesterase InhibitorNervous system, lungsMuscle twitching, breathing issues, seizures
Ethylene Oxide (used in sterilizers, antifreeze)Carcinogen, Mutagen, Reproductive ToxinDNA, reproductive systemGenetic mutations, miscarriages, cancer risk
  • Carcinogen: Causes cancer.

  • Mutagen: Causes genetic mutations that may lead to disease or birth defects.

  • Neurotoxin: Affects the brain and nervous system.

  • Reproductive Toxin: Affects fertility or fetal development.

  • Irritant: Causes inflammation of skin, eyes, or lungs.

  • Asphyxiant: Interferes with oxygen supply to the body.

  • Over 30% of workplace chemical injuries happen because workers weren’t aware of the chemical’s risks — or didn’t recognize the hazard symbol on the label.

  • The Globally Harmonized System (GHS) uses 9 standard pictograms to communicate chemical hazards. If you understand the symbols, you can quickly know if a product is flammable, toxic, corrosive, or explosive — even without reading the label in full.

  • Carbon monoxide is called the "silent killer" because it's colorless, odorless, and deadly. It binds to red blood cells 200 times more strongly than oxygen, starving your body and brain of air.

  • Benzene, commonly used in paints and glues, is a known carcinogen. Just prolonged inhalation in poorly ventilated spaces can increase leukemia risk.

  • Many cleaning products contain ammonia and bleach — but mixing them creates toxic chloramine gas, which can lead to unconsciousness or death in minutes.

  • Always read chemical labels and Safety Data Sheets (SDS) before handling any substance.

  • Recognize hazard pictograms to quickly understand chemical risks.

  • Know the common chemicals in your workplace and their target organs.

  • Use the correct Personal Protective Equipment (PPE) for each chemical.

  • Never mix incompatible chemicals (e.g., bleach and ammonia).

  • Employers must provide training, labeling, and access to SDS for all hazardous chemicals.

  • Stay informed — your right to know is key to staying safe!
