MODULE 5 OF 12

Health and Safety

Security guards must understand workplace health and safety principles to protect themselves, their coworkers, and the public. This module covers the OHSA, worker rights, WHMIS 2015, workplace hazards, and workers' compensation procedures.

5.2 — The Occupational Health and Safety Act (OHSA)

The Occupational Health and Safety Act (OHSA) is Ontario's primary workplace health and safety legislation. It establishes the rights and responsibilities of employers, supervisors, and workers to maintain safe and healthy workplaces. Security guards should familiarize themselves with the OHSA and its regulations — commonly referred to as the "Green Book" (the 2020 Ontario OHSA and Regulations for Construction Projects).

5.3 — Three Fundamental Worker Rights

Every worker in Ontario is entitled to three fundamental rights under the OHSA:

1
The Right to KnowWorkers have the right to know about workplace hazards, including chemical, physical, biological, and ergonomic hazards.
2
The Right to ParticipateWorkers have the right to participate in health and safety matters through a Joint Health and Safety Committee (JHSC) or health and safety representative.
3
The Right to Refuse Unsafe WorkWorkers have the right to refuse work they believe is dangerous to themselves or another worker, without reprisal from the employer.

5.4 — The Right to Refuse Unsafe Work: Detailed Procedure

A worker cannot be fired or disciplined for exercising the right to refuse unsafe work.

  • Definition of "imminent danger": A danger that is not normal for that type of work, or a danger under which a worker would not normally carry out the work.
  • The worker is still entitled to receive pay during the investigation period.
  • The worker may be assigned alternate tasks that are safe while the refusal is being investigated.
  • If the worker believes the situation is still unsafe after the supervisor's investigation, they can file a complaint with the Health and Safety Representative.
  • A Health and Safety Officer will investigate and issue a written decision.
  • The worker has the right to appeal to the Occupational Health and Safety Council.

5.5 — Workplace Hazardous Materials Information System (WHMIS 2015)

WHMIS 2015 is Canada's national hazard communication standard. It provides workers with information about hazardous materials in the workplace through labels, Safety Data Sheets (SDS), and worker education. Key hazard classes include:

Class B: Flammable and Combustible MaterialSolids, liquids, and gases capable of catching fire or exploding under specific conditions.
Class C: Oxidizing MaterialMaterials that increase the fire risk when they come into contact with flammable or combustible materials.
Class D: Poisonous and Infectious Material — Division 1Materials Causing Immediate and Serious Toxic Effects (e.g., sodium cyanide, hydrogen sulphide).
Class D: Poisonous and Infectious Material — Division 2Materials Causing Other Toxic Effects — life-threatening or serious long-term health problems including cancer, reproductive harm, or sensitization.

The NFPA Diamond

The National Fire Protection Association (NFPA) diamond is a standardized hazard identification system used on buildings, storage areas, and containers. Each quadrant uses a colour to indicate a specific hazard type:

BlueHealth hazard
RedFire hazard
YellowInstability / reactivity hazard
WhiteSpecific hazard (e.g., oxidizer, water-reactive)

5.6 — Eight WHMIS Hazard Symbols (GHS Pictograms)

Under WHMIS 2015, the following hazard symbols must be recognized by all workers. Employers are legally required to train workers to recognize and respond appropriately to all WHMIS hazard symbols.

1
FlameFlammable materials
2
Flame over CircleOxidizers
3
Gas CylinderCompressed gases
4
CorrosionCorrosive to metals, skin, or eyes
5
Skull and CrossbonesAcute toxicity (fatal or toxic)
6
Health HazardSerious health effects (carcinogen, respiratory sensitizer, reproductive toxicity)
7
Exclamation MarkIrritant, skin sensitizer, narcotic effects
8
EnvironmentAquatic toxicity (hazardous to the environment)

5.7 — Safety Data Sheets (SDS)

A Safety Data Sheet (formerly MSDS) provides critical information about hazardous materials:

What the hazardous material is (identification, composition)
How it is hazardous to humans (health effects, routes of exposure)
How to work safely with it (handling, storage, protective equipment)
What to do in an emergency (first aid, spill procedures, firefighting measures)

Employers must provide training to workers on:

  • Reading WHMIS labels
  • Accessing and reading the Safety Data Sheet
  • Safely using hazardous materials
  • Storing and disposing of hazardous materials
  • Emergency procedures for spills, releases, fires, and poisoning
  • Using personal protective equipment

5.8 — Other Workplace Hazards

Security guards may be exposed to a variety of workplace hazards:

Safety HazardsMachines, equipment (chainsaws, forklifts, ladders), slippery surfaces, falling objects.
Biological HazardsHIV/AIDS, Hepatitis A/B/C, Rabies, and other infectious agents that may be encountered through bodily fluids or contaminated materials.
Physical HazardsCold, humidity, heat, noise, vibration, radiation.
Ergonomic HazardsCarpal Tunnel Syndrome, Tennis Elbow, and injuries resulting from pushing, pulling, lifting, and shoveling.
Stress and ViolenceBullying, threatening behavior, verbal and physical harassment.

5.9 — Working Alone Hazards

Many security guards work alone, which presents unique hazards. Employers must inform workers who work alone about their specific risks. Workers who commonly work alone include taxi drivers, retail workers, home care workers, security guards, and custodians. Employers must develop procedures to check on the well-being of lone workers at regular intervals.

5.10 — Workers' Compensation (WSIB)

The Workplace Safety and Insurance Board (WSIB) provides compensation and support to workers injured on the job:

  • If injured at work or sick from a work-caused disease, you may qualify for benefits.
  • WSIB decides eligibility and compensation.
  • Worker's Report of Injury Form — Send to WSIB as soon as possible.
  • You can have another person help fill in the form.
  • You can contact WSIB to learn about your compensation status at any time.

5.11 — In Case of Injury at Work: Step by Step

  1. 1

5.12 — Reporting Injuries: Detailed Procedure

  • Get first aid and report to your supervisor immediately.
  • See a doctor; let them know it is a work injury.
  • At workplaces without first aid facilities, see a doctor immediately.
  • Employer pays travel costs to the doctor or hospital.
  • Tell the doctor how the injury is work-related — give a detailed account.
  • Report main and minor injuries — some injuries develop over time.
  • Always report the accident to your employer even if there is no apparent injury at the time.
  • The employer may be required to report to WSIB within 72 hours.

5.13 — While Off Work Due to Injury

  • Speak with WSIB before changing doctors.

  • You can appeal and ask WSIB to change its decision if you disagree.
  • The Appeals Commission provides free assistance with the appeals process.
  • You can get a copy of your WSIB file from the Access to Information unit.
