Workplace Health and Safety Management Systems
Put in place to deal with 5 types of hazards:
• Ergonomics• Physical• Psychosocial• Chemical• Biological
5 Hazard Identification categories
• are present when a worker is exposed to any chemical preparation in the workplace in any form (solid, liquid or gas)
• liquids like cleaning products, paints, acids, solvents especially chemicals in an unlabelled container (warning sign!)
• vapours and fumes, for instance those that come from welding or exposure to solvents
• gases like acetylene, propane, carbon monoxide and helium
• flammable materials like gasoline, solvents and explosive chemicals.
• Do’s:• -Read labels and MSDSs to learn special handling procedures• -Mix corrosives and solvents slowly• -Add acid to water, not water to acid• -Use the right PPE for each chemical• -Know how the use the PPE if needed• -Wash your hands when done• -Use proper ventilation• -Know first aid procedures
• Don’ts• -Sniff a chemical to identify it• -wear contact lenses, they can absorb
chemicals into your eyes• -Put your hands into corrosives and
solvents without gloves• -Use a chemical if you don’t know what
it is• -Skip safety precautions to finish quicker
• include unsafe conditions that can cause injury, illness and death.• Examples of physical hazards include:• electrical hazards: frayed cords, missing ground pins, improper
wiring• unguarded machinery and moving machinery parts: guards
removed or moving parts that a worker can accidentally touch• constant loud noise• high exposure to sunlight/ultraviolet rays, heat or cold• working from heights, including ladders, scaffolds, roofs, or any
raised work area• working with mobile equipment such as fork lifts (operation of
fork lifts and similar mobile equipment in the workplace requires significant additional training and experience)
• spills on floors or tripping hazards, such as blocked aisle or cords running across the floor.
Physical Hazards
Physical Hazards
• Do’s• -Put chemical wastes in a covered
waste container.• -Keep a fire extinguisher close to where
you are working.• -Be aware of all possible hazards
around you• -Pay attention to what you are doing• -Keep sparking tools away from
flammable chemicals.• -Cut away from yourself when using
knives and other sharp tools
Physical Hazards
• Don’ts• -Carelessly dispose of harmful
chemicals• -Smoke in the workplace• -Leave tools and boxes around • -Leave drawers open• -Place items on the stairs• -Cut towards yourself when
using knives• -work without or remove
guards from equipment
Biological Hazardcome from working with animals, people or infectious plant materials. Work in day care, hospitals, hotel laundry and room cleaning, laboratories, veterinary offices and nursing homes may expose you to biological hazards.
•blood or other body fluids•fungi•bacteria and viruses•plants•insect bites•animal and bird droppings.
Biological Hazard
• Do’s• -Work on equipment if
clearance form is attached
• Keep safety clearance forms with equipment at all times
• Ask any questions you might have
• Wear proper PPE
Biological Hazard
• Don’ts• Accept equipment
without safety clearance• Work on equipment with
the safety clearance form attached
• Remove equipment from the lab if it still has hazard labels on it
• Occur when concerns in the workplace include excessive working time and bullying. Another occupational psychological hazard is sexual harassment
• Taunting by co workers or others• Excessive pressure to complete tasks or duties• Bullying• Sexual harassment• Too much overtime and workload
• Do’s• -Report any bullying or harassing of any kind to the
management• - Get enough sleep at night so you can do your job
properly and aren’t overtired• -Tell management if you are feeling over stressed.
• Don’ts• -Let harassment slide• -Bully or harass other
employees• -Go to work if you are
stressed out or sick
• occur when the type of work, body position and working conditions put strain on your body
• poor lighting• improperly adjusted workstations and chairs • frequent lifting • poor posture • awkward movements, especially if they are repetitive • repeating the same movements over and over • having to use too much force, especially if you have to do it frequently
Do’s•-Sit in a position that is comfortable for you•-Make sure your chair is the right height of you•-Only lift and push things that you know you are capable of moving
• Don’ts• -Sit in an improper
position• -Lift too much
weight for yourself• -Do something you
know you are not capable of doing
• Commitment from senior management is essential for the health and safety management system to be effective.
1. Clearly demonstrated and management commitment, and
written company policy
• Evaluation of all equipment, machinery, work areas and work processes to identify and analyze all potential sources of harm to workers.
2. Identification and analysis of health and safety hazards at the work site
• Control measures include: engineering controls, administrative controls and personal protective equipment
3. Control measures to eliminate or reduce the risks to workers from
hazards.
• Inspections are an opportunity to identify any hazards that have not been recognized before, and to check that existing hazard controls are working.
4. Inspection program
• Workers need to know how to do their jobs safely and without risk to their health; new and/or young workers need special attention.
5. Worker competency and training
• Emergencies could include natural or manmade disasters as well as health emergencies or injuries. Effective plans need to be in place to address all potential emergencies
6. Emergency response planning
• When an incident occurs at any workplace it is important to investigate so that any inadequately controlled hazards are identified and controlled and processes can be put in place to prevent the recurrence of similar incidents.
7. Incident reporting and investigation
• Program administration ensures that all parts of a health and safety management system are properly looked after and communicated to employees
8. Management system administration
• PPE (personal protective equipment) are things that must be worn for the job you are doing.
• PPE can include: hardhats, safety glasses, work gloves, steel toed boots, ear plugs, and masks .
• It is mandatory that workers where PPE when needed or they can be fired or punished by the management.
WHMIS TRAINING
INTRODUCTION• WHMIS Training will help employees gain
the ability to recognize hazardous products used on the work site
• Once hazardous products are recognized training will assist employees how to:
1. Locate information on the hazards and 2. Utilize proper handling techniques for
these materials
LEGISLATION• WHMIS is enforced by a combination of federal
and provincial legislation.
Federal legislation requires suppliers/importers of hazardous materials (controlled products) to provide adequate labels and MSDSs as a condition of sale and importation.
• Federal, provincial, and territorial Occupational Safety and Health (OSH) legislation requires employers to provide labels, MSDSs, and worker education programs in the workplace.
HAZARDOUS PRODUCT ACT The Hazardous Product Act has issued
regulations identifying:
1. What is a controlled product?2. Material Safety Data Sheets [MSDS]
required for the sale of controlled product3. Information to be disclosed on an MSDS4. Ingredient disclosure and identity5. Labeling requirements of controlled
products
CONTROLLED PRODUCTS REGULATIONS
A “Controlled Product” is defined as:Any product, material or substancedetermined in accordance with Part IV of the Controlled Products Regulations to be included in the classes listed in Schedule II ofthe Hazardous Products Act.
WHMIS
WORKPLACE HAZARDOUS MATERIALS I NFORMATION SYSTEM
WHMIS OBJECTIVES
• Identify Hazardous materials on the work site
• Improve the communication of health hazard information of materials used on the work site
• Protect employees from exposure to hazardous materials through safety equipment, training, and procedures

Job SafetyAnd The Law
It is against the law for anyone to force you to do work that you think is unsafe.
For example: If you or a co-worker are in imminent danger.
OH&S ActEach province in Canada has it’s own Act. It specifies the safety standards designed to protect the health and safety of workers.
• It also includes the rights and duties required of both the employers and of the workers.
In Alberta:
• both employers and workers are responsible for safety in the workplace
An employer is:
A) a person who employs one or more workers or
B) A person who is self-employed
A worker is:• Any person
working at a job.
• You need to know your rights
• and what is expected of you.
Imminent Danger
Any danger that is not normally found in the job, or a danger under which a person doing that job would not normally carry out his/her work.
Who is covered by the OH&S Act?Most workers and employers, except:•Domestic workers ( such as nannies or housekeepers).•Federal government workers•Workers in industries regulated by the federal government ( banks, television and radio broadcasters, national transportation companies).•Farmers and other agricultural workers.
You employer must look after you safety!
They must:•Make sure workers are competent (make sure you have the training to do the job well).•Provide the safety equipment and training.•Train workers to handle dangers or dangerous products.•Investigate accidents that cause serious injuries/incidents that could cause serious injuries.
Every Worker Shall:• Take reasonable care to
protect his/her own health and safety as well as the other workers present while at work and…
• Co-operate with the employer to protect the health and safety of self and other workers at the workplace.
WCB
WCB-Alberta’s mandate
• The Workers’ Compensation Board is a statutory corporation created by government under the Workers’ Compensation Act to administer a system of workplace insurance for the workers and employers of the province of Alberta. The organization is employer funded to provide cost-effective disability and liability insurance.
We are committed to fairness
• We protect employers and workers from the uncertainty, cost and delays of legal action by providing no-fault coverage.
• We compensate injured workers for lost employment income.
• We cover the cost of health care and other costs associated with a work-related injury or illness.
• We add stability to the compensation system through the balanced application of the Workers’ Compensation Act.
We focus on return to work
• We support workers’ safe return to work through case plans that set clear goals.
• We help employers bring their workers back to work through strong disability management and modified work programs.
Risk and Hazard Assessment
What is a Hazard?
• A hazard is anything that can cause injury or loss.
Three Steps to Controlling Hazards
• Identification: Seeing a hazard and knowing what it is
• Assessment: knowing the risk of each hazard• Control: what may be done to limit the hazard
from causing harm or loss
Hazard Elimination and Control
• Elimination: removing the hazard• Control: having a plan to reduce the risk of the
hazard• Three main types of Hazard Control:• Engineering- ie. Improving ventilation,
adjusting work area• Adminstrative- ie. Training workers• Basic controls- PPE- last resort
Ladder Safety and Preventing Falls
Ladder Types Type I-A ladders are heavy-duty
and can handle up to 300 lbs. Type I ladders can hold up to 250
lbs. Type II ladders can hold 225 lbs. Type III ladders are for light duty
only and can hold up to 200 lbs.
An AccidentWhat Happened
• A fiberglass A-frame ladder split halfway up the ridge of the leg rail, causing a worker on the ladder to fall to the rig floor.
• The employee injured his wrist.
What Caused It• An investigation showed the ladder appeared to be in good
shape and not misused.
• It appeared to be a lighter shade than the other ladders on location, suggesting that it had been left out in the sun.
• When the ladder was standing alone, without weight on it, the split was extremely hard to see.
Ladder Inspection
Rungs must be intact and free from grease or oil.
Make sure there are no splinters or sharp edges.
See that metal ladders are not dented or bent.
Ladder Inspection
Safety feet should be in place.
All support braces and bolts must be present and secure.
On extension ladders, make sure rope is not torn or frayed.
Ladder Inspection
On stepladders, make sure the hinge spreader is working properly.
Tag Defective Ladders
• These ladders are properly tagged “Do Not Use”
Know the rules!
Ladder Don’ts Do not use ladders that have been exposed to
fire or corrosive chemicals. Do not use a ladder for unintended purposes,
such as in place of scaffolding. Never allow more than one person on a
ladder at a time.
Read The Warning Labels
• They are there for a reason!
Use of Step Ladders
Use of Step Ladders Always set
level.
Be sure latches are down.
Proper Ladder Climbing
• Use both hands to climb a ladder. • Always face the ladder when climbing,
descending or working. • Avoid the top two steps of a stepladder
and the top four rungs on other ladders.
Don’t Lean a Step Ladder
• The support leg (arrow) can contact the ground causing the step leg to kick out.
• Also employees should not work from the top or second step.
Don’t Lean!• Avoid excessive
stretching or leaning.
• Workers should never work with one leg on a ladder and one off.
• A slip could result in serious fall.
NO!
Do Not Stand On The Top Step!!!
Obey The Labels!!
Top Step!?!?!
Safe Step Ladder Use
• Always face the ladder
• Stay off top two steps.
Unsafe Step Ladder Use
• Do not straddle the top unless the ladder is designed for it.
NO!
Working Above Protections
• When employees work above railings, they must be protected from falling over the railings.
Working on Upper Levels
Safe Step Ladder Use
• When working to the side, maintain balance.
Self Supporting Ladder
Use of Extension Ladders
Set Feet Properly
Firm BaseSet both feet level and on
the pads
Soft BaseSet on the spikes and seat the ladder in the
ground.
Not a Firm Foundation
Proper Ladder Set
• Make sure the ladder's feet are parallel to the surface it rests against.
• Don’t set ladders where they may be hit or dislodged.
Set The Proper Angle The distance from the
bottom of the ladder to the wall should be one-fourth of the ladder's working height.
An extended arm will be close.

Check The Locks
• Always check to be sure the extension locks are properly seated.
This Is A Poor Set Up
• The top could fall out with any slip at the base.
• The angle is too steep.
Working From a Ladder• Always face the
ladder.• Keep one hand on
the ladder for hold.
• Do not work on top four steps.
• Work within easy reach.
Ladder Access
• Many workers fall from ladders while accessing to another work area.
Ladder Access
• These are a very poor and hazardous set ups!
NO!
Extend Above Platform
• Access ladders must extend at least 3 feet above the landing platform.
3 feet
Proper Access Ladders
• Ladders should be set at 1 horizontal to 4 vertical.
• Ladders must be secured.
• Ladder access ways must be guarded.

1
Securing Ladders• This ladder is tied
with a rope to a horizontal girt.
• There is nothing to keep the rope from sliding on the girt allowing the ladder to move laterally.
Ladders Near Electrical
• Use non-conductive ladders.
• Don’t carry or move extension ladders while extended.
• Get help moving ladders to maintain control.
Slips, Trips & Falls
• The #1 cause of office employee injuries! – 265,000 nonfatal injuries from slips, trips, and falls
annually result in one or more days away from work per incident
– Slips, trips, and falls result in 17% of all nonfatal workplace injuries per year, the highest injury rate of any regulated activity
Fall Hazards
• Storage or placement of objects in aisles, below knee level, or on other “office-type” floor surfaces.
• Cords, ropes, hoses across floors and walkways• Overflowing, heavy wastebaskets.• Dust accumulations.• Open drawers and doors• Wet floors
Aisles and Passageways– Keep clear for
material handling equipment
– Mark permanent aisles
– Heavy-traffic passage-ways must be equipped with pedestrian walkways
Slips & Trips
• It is also possible to injure your back slipping on a wet floor, ice, muddy ground, etc.
• Poor housekeeping is a common cause.
Basic Safety STEPS
• Awareness.• Keep aisles clear.• “Walk like a duck” on slippery surfaces.• Use the handrail on stairs.• Hold onto chair seats/arms when attempting to
sit.• “Sensible shoes.”• Wipe up spills.• Walk, don’t run.
Use Stairs Safety
– Use handrails– Walk—don’t run– Inspect for slippery
surfaces or damaged steps
– Do not put objects on steps
– Do not carry bulky objects on stairs
Keep Walking and Working Surfaces Clear and Clean
• Keep workroom floors clean and dry
• Maintain a clean and orderly work area
Eliminate Trip Hazards
– Pick up tools, materials, and trash
– Pick up or walk around obstructions
– Report dangerous walking and working surfaces
– Keep file drawers closed – Keep power cords out of
walkways
Eliminate Slip Hazards
– Clean up liquids– Sweep up debris and dust– Stop and repair leaks – Install absorbent around wet processes– Use warning signs or cones
Wear Slip-Resistant Shoes
– Street shoes not intended for slip resistance
– Soft rubber sole for slip resistance
– Sole tread with channels
– Still need to walk carefully
Be Alert, Use Common Sense
– Be aware of the hazards– Pay attention to where you are going– Adjust your stride according to the
walking surface– Make wide turns at corners– Don’t block your vision when carrying
items
Incipient Stage Fire ExtinguisherTraining
Purpose of a Fire Extinguisher
Two functions:1. To control or extinguish small or incipient stage fires and, 2.To protect evacuation routes that a fire may block directly or indirectly with smoke or burning/smoldering materials.
Definitions
OSHA"Incipient stage fire" means a fire which is in the initial or beginning stage and which can be controlled or extinguished by portable fire extinguishers, Class II standpipe or small hose systems without the need for protective clothing or breathing apparatus.
NFPA“Incipient stage fire” A fire is considered to be beyond the incipient stage when the use of thermal protective clothing or self contained breathing apparatus is required or an industrial fire brigade member is required to crawl on the ground or floor to stay below smoke and heat.
What type of Fire do I have?
Fire requires 3 Elements
1.Heat: Without sufficient heat, a fire cannot begin, and it cannot continue.
2.Fuel: Without fuel, a fire will stop.
3.Oxygen: Without sufficient oxygen, a fire cannot begin, and it cannot continue.
Match your Fire Extinguisher to the Type of Fire you are anticipating
5 Categories of Fires
– Class A Fires: Ordinary combustible materials such as wood, cloth, paper, rubber and many plastics.
– Class B Fires: Flammable Liquids, combustible liquids, petroleum greases, tars, oils, paints, solvents, lacquers, alcohols and flammable gases.
– Class C Fires: Involve electrical equipment.
– Class D Fires: Involve combustible metals, such as magnesium, titanium, zirconium, sodium, lithium and potassium.
– Class K Fires: Involve cooking appliances that involve combustible cooking media (vegetable or animal oils/fats)
6 Types of Fire Extinguishers1. Fire Extinguishers should be appropriately
matched to work environment.
2. Use the symbols to quickly identify the Type of Fire Extinguisher.

off.
General Procedures for Responding To a Fire
1. SOUND THE FIRE ALARM and call the fire department, if appropriate.
2. IDENTIFY A SAFE EVACUATION PATH before approaching the fire.
– Do not allow the fire, heat, or smoke to come between you and your evacuation path.
3. SELECT the appropriate type of fire extinguisher.
4. DISCHARGE the extinguisher within its effective range using the P.A.S.S. technique (pull, aim, squeeze, sweep).
5. BACK AWAY from an extinguished fire in case it flames up again.
6. EVACUATE IMMEDIATELY if the extinguisher is empty and the fire is not out.
7. EVACUATE IMMEDIATELY if the fire progresses beyond the incipient stage.
When it is Safe to Fight a Fire
When it is NOT Safe to Fight a Fire
How to Extinguisher a Small FirePASS
1. “P”ULL... Pull the pin. This will also break the tamper seal.
2. “A”IM... Aim low, pointing the extinguisher nozzle (or its horn or hose) at the base of the fire.
Note: Do not touch the plastic discharge horn on CO2 extinguishers, it gets very cold and may damage skin.
3. “S”QUEEZE... Squeeze the handle to release the extinguishing agent.
4. “S”WEEP... Sweep from side to side at the base of the fire until it appears to be out. Watch the area. If the fire re-ignites, repeat steps 2 - 4.
If you have the slightest doubt about your ability to fight a fire....EVACUATE IMMEDIATELY!
Pull the Pin (straight out)
Quickly Check the Pressure Gauge
Pick up the Fire Extinguisher with your least favorite hand.Support the bottom with your strong hand.
Know what you are looking for….
A fully charged Fire Extinguisher has the arrow in the green section…
Remove the nozzle from the clip.
Hold the nozzle with your strong hand.
Carry the Extinguisher with your opposite hand.
Squeeze the handle gently to test the Extinguisher.
Begin your approach from a Safe Distance
Aim at the Base of the Fire
Sweep Back and Forth to cover the width of the fire
Direct the nozzle so the agent falls directly onto the burning metal.
Close the nozzle valve to produce a soft, heavy flow and move closer to cover the fire area.
Do not disturb the agent and fire until it has cooled.
