Non-point (diffuse) sources

Occur over a wide area and are associated withparticular land uses (e.g. agriculture)

Air Pollution

A mix of particles and gases that can reach harmful concentrations both outside and indoors

(T/F) In Ontario, the Ministry of Economic Development is responsible to monitor and enforce WHMIS.

True • False •

False it is the Ministry of Labour, Immigration, Training and Skills Development (MLITSD)

Criteria Air Contaminants (CAC)

A set of air pollutants that cause smog, acid rain, and other health hazards. Mainly products of fossil fuel combustion

Ergonomics

Ergonomics is the science of matching the job to the worker and the product to the user. It covers situations such as lifting, lighting, office/desk setup, etc., that may contribute to injury.

Fire Safety Plan

A detailed document that covers all aspects of fire safety for a specific building or property. The plan outlines

1. A safe and orderly way for occupants to evacuate the building.

2. Proper maintenance and housekeeping required to prevent fires

3. Methods of control that minimize the damages of fire when it occurs

4. They are required by the local fire code, especially for certain buildings and occupancy rates.

Accident Theory

the study of failures within a management system or human error. It allows safety professionals to better understand why accidents happen and how to design a management system to prevent them.

Main Components of WHMIS

Hazard identification and product classification, Labelling, Safety data sheets, Worker education and training

Is a WHMIS a Law T/F?

True

A supplier is?

is "a person who, in the course of business, sells or imports a hazardous product"

An importer is?

is "a supplier who brings a hazardous product into Canada, but does not sell the product,

A manufacturer is?

is "a supplier who, in the course of business in Canada, manufactures, produces, processes, packages or labels a hazardous product and sellsit"

A distributor is?

is "a Canadian supplier to whom a hazardous product was sold, and who then resells the hazardous product without modifying it.

Food Safety

Food safety is the science of handling, preparing and storing food to reduce the risk of food borne illnesses.

In Ontario, the five most commonly reported types of bacteria causing foodborne illness are campylobacter, listeria, salmonella, E. coli and Yersinia.

Radiation energy

The energy related to ionizing, low-frequency electromagnetic, optical, or radio-frequency electromagnetic radiation. Effects depend on radiation levels and length of exposure and may include skin burns,acute radiation syndrome, cardiovascular disease, and changes to genetic material, which may lead to cancer

Mechanical energy

The energy contained in an item under tension. For instance, a spring that is compressed or coiled will have stored energy which will

Gravitational potential energy

The energy related to the mass of an object and its distance from the earth (or ground). The heavier an object is, and the further it is from the ground, the greater its gravitational potential energy. For example, a 1 kilogram weight held 2 metres above the ground will have greater gravitational potential energy then a 1 kilogram weight held 1 metre above the ground.

Hydraulic potential energy

The energy stored within a pressurized liquid.When under pressure, the fluid can be used to move heavy objects, machinery, orequipment. Examples: automotive car lifts, injection moulding machines, powerpresses, and the braking system in cars.

Pneumatic potential energy:

The energy stored within pressurized air.Pneumatic systems are generally powered by compressed air to power equipment.Examples include spraying devices, power washers, rock drills, and riveters.

Chemical energy:

The energy released when a substance undergoes a chemical reaction. The energy is normally released as heat, but could be released in other forms, such as pressure. A common result of a hazardous chemical reaction is fireor explosion.

Thermal energy:

The energy from an explosion, flame, objects with high or low temperatures or radiation from heat sources. Common injuries include burns,

Hazardous Energy

Hazardous energy is defined: "any electrical, mechanical, hydraulic, pneumatic, chemical, nuclear, thermal, gravitational, or other energy that can harm personnel"

Most common type of energy used in a workplace?

Electrical energy is the most common form of energy used in workplaces. It can beavailable live through power lines or it can also be stored, for example, in batteries orcapacitors.

What is a Physical Agent

Physical agents are sources of energy that may cause injury or disease. Examples include noise, vibration, radiation, and extremes in temperature.

Workplace Health and Disability

Employee Assistance Services (EAS) offers customized services, on a cost recovery basis, to help managers and employees deal with mental health related issues

Total Worker Health

Policies, programs, and practices, that integrate protection from work-related safety and health hazards with promotion of injury and illness prevention efforts to advance worker well being.

Psychosocial Hazard

Factors in work design, organization, management or the social context of work/life that have the potential for psychological or physical harm (stress).

Direct Ecosystem Changes

Occur with some immediacy, through locally identifiable biological or ecological pathway (building a dam can increase mosquito breeding and increase malaria transmission)

Indirect Ecosystem Changes

Take a toll on well-being through complex webs of causation and may take decades to have an impact

Nautral Air Pollution

Largest sources of many pollutants. Have less long-term adverse effects because they come from widely dispersed sources or infrequent events (volcanoes are the expect ion)

Anthropogenic Air Pollution

Emit large quantities of pollutants in restricted areas (cities) and contribute to high concentrations at a local area.

Waterborne Diseases

Contamination of water by human/animal feces or urine infected by pathogenic viruses or bacteria; directly transmitted when water is consumed or used in preparing food.

Water-washed Diseases

A lack of access to safe water supplies leads to infrequent washing or inadequate personal hygiene that then results in disease/illness

Water-based Diseases

Water provides the habitat for intermediate host organisms where parasites can pass through their life cycle; later these parasites can infect humans in larval forms, by boring into the skin or being injected.

Water-related diseases

Water provides the habitat for vectors of disease (mosquitos require water to reproduce)

Water-dispersed Infections

Infections can proliferate in water and enter the body through the respiratory tract

Hazardous Chemical

Any chemical that presents a physical hazard (combustible liquid, compressed gas, explosive, oxidizer, pyrophoric, etc) or health hazard (chemical has acute or chronic health effects when exposed to: reproductive toxins, corrosives, hepatotoxins, nephrotoxins, neurotoxins, sensitizers, etc)

Heinrich’s Safety Pyramid

Concept in workplace safety that demonstrates a correlation between near misses, minor injuries, and major accidents (Unsafe acts, near miss, minor injury, lost time/serious injury, fatality)

Maternal/Reproductive Health

Pregnant women often face heightened risk during extreme weather events. Can lead to complications during childbirth and limited access to maternal healthcare services.

Displacement/Migration

Climate-induced displacement can lead to overcrowded or unsanitary living conditions, resulting in a higher risk of exposure to infectious diseases and limited access to healthcare and education.

OHS Rights and Responsibilities

1. Right to Know (Know what you’re getting into during the job)

2. Right to Participate (Identifying hazards, going to H&S committee, communicate concerns)

3. Right to Refuse (Can refuse dangerous workers, jobs like firefighters and healthcare workers don’t have this right)
