Material Safety Data Sheets (MSDS) must be: a) Made available to all workers by the employer b) Less than 3 years old c) Made available in English and French by the supplier d) All of the above RATIONALE: The MSDS is part of our right to know. Therefore, they must be easily accessible, easy to read, and have up-to-date information. 4. For a fully or partially enclosed space to be designated as a confined space under the Occupational Health & Safety Act, it must meet only ONE of the following conditions: i. not designed and constructed for continuous human occupancy, and ii. in which atmospheric hazards may occur because of its construction, location or contents or because of work that is done in it a) True b) False RATIONALE: Section 1 of Regulation 632/05 for Confined Spaces states that both of these conditions must be met for a partially or fully enclosed space to be considered a confined space for most workplaces covered under the Occupational Health & Safety Act. 5. A confined space attendant has which of these responsibilities: a) Log the entrants in and out b) Remain at the entrance while workers are inside c) Keep in constant contact with the entrants d) All of the above RATIONALE: These are just a few of the duties. Others include; monitoring the safety of the worker, providing assistance to the worker and summon an adequate rescue response if required. 6. Confined spaces, including tanks, vessels, pits, and trenches/manholes/sumps deeper than 4 feet, can be dangerous because of: a) Poor access or exit b) Slick or wet surfaces c) Reactive or corrosive residues d) Oxygen-rich or –deficient atmospheres e) All of the above RATIONALE: Confined spaces can be subject to both physical and atmospheric hazards.

A safety attendant shall not enter a confined space at any time: a) True b) False RATIONALE: Section 15(2) of the Confined Space regulation states that no attendant shall enter a confined space at any time. The attendant’s role is to monitor the safety of the worker inside; to provide assistance to him or her from outside the confined space; and to summon an adequate rescue response if required. 8. Bicycles pose hazards in and around the plant sites to the riders, to pedestrians, and to drivers of other vehicles. a. True b. False RATIONALE: Bicycles can be hard to spot by both pedestrians and other drivers, especially if the bicycles are being driven in areas where they aren’t expected, such as through work areas or on walkways. Cyclists need to be aware of their surroundings at all times and proceed with caution. 9. Which of the following are significant hazards to drivers? a) Hidden intersections b) Following too closely c) Cyclists driving in areas meant for pedestrians d) Railway crossings e) All of the above RATIONALE: You may come across these hazards while operating any type of vehicle on the job, whether on municipal/provincial roadways or roadways inside plant property. Pay particular attention when approaching these hazards. 10. Equipment operators who drive on soft ground around designated walkways could create trip & fall hazards: a) True b) False RATIONALE: Tire tracks from heavy equipment can leave ruts in soft ground, which may lead to trip injuries such as sprained joints and broken bones. Operators should avoid driving on soft ground and pedestrians should be mindful of soft walking surfaces when there are no designated walkways. 11. More slips/trips/falls happen while working at the same level than from working at height. a) True b) False RATIONALE: Statistics show that 65% of falls are from the same level compared to 35% of falls are from working at height. In addition, 1/3 of all lost time injuries happen when workers fall to the same level they’re standing or walking on.

Some conditions that could lead to a slip, trip or fall might be… a) Poor housekeeping b) Walking backwards c) Slippery surfaces d) Texting while walking e) All of the above RATIONALE: The first step in preventing falls is to be aware of your surroundings and identify all the potential slip, trip, and fall hazards for every job you do. 13. Which of the following is NOT true regarding cold stress? a) It can lead to frostbite and hypothermia. b) Effective controls can include proper clothing, rest/ warm-up breaks, and training and instruction in safety and health procedures. c) It occurs when the body is unable to warm itself d) Some of the signs/symptoms include poor co-ordination, blue lips and fingers, reduced mental alertness and shivering e) None of the above RATIONALE: These are all true of cold stress. Cold is a physical hazard and presents a very real danger to workers. Prolonged exposure to cold eventually depletes the body’s energy reserves and affects the brain’s ability to function properly. Never compound the risk by going off by yourself in the cold. 14. Ergonomic hazards can lead to what type of injuries/illnesses? a) Chemical burns b) Sprains and strains to joints, muscles, ligaments and tendons c) Slip and fall injuries d) Lacerations and amputations RATIONALE: Ergonomic hazards can lead to injuries of the musculoskeletal system.

Under the Occupational Health and Safety Act, a “right” is something you have the choice to do while a “responsibility” is something you must do. a) True b) False RATIONALE: The main purpose of the Occupational Health and Safety Act is to protect the health and safety of workers. Responsibilities for workplace parties are written into the Act and regulations and are enforced by the Ministry of Labour, and worker rights are protected by the Act. 17.

The employer has a responsibility to provide you with information and instruction to protect the health and safety of the workers, which can be accomplished through formal training as well as verbal or written forms of communication. 19. The Joint Health & Safety Committee and health & safety representatives have the power to identify workplace hazards, obtain information from the employer, and make recommendations to the employer for the control of hazards. These are expression of your right to… a) Know b) Participate c) Refuse RATIONALE: The most significant way to exercise your right to participate in workplace health and safety, depending on the size of your workplace, is either by joining your Joint Health and Safety Committee or by becoming a health and safety representative.

If one or more designated substances are present in a workplace, the employer is responsible for implementing a control program that includes a written plan for each specific substance. 21. One of the most common results of exposure to designated substances is various forms of cancer: a) True b) False RATIONALE: Exposure to designated substances can cause permanent damage to the human organ systems, including the liver, the lungs, and the reproductive and nervous systems. Many of the designated substances are known carcinogens, leading to various forms of cancer such as mesothelioma from long-term exposure to asbestos, and leukemia from long-term exposure to benzene. 22. Silica-containing dust can be generated during such activities as grinding, jack-hammering, concrete drilling, and abrasive blasting with sand. a) True b) False RATIONALE: Silica dust will be emitted into the air so proper PPE should be worn when performing these tasks. 23. The most common form of exposure to mercury is through vapour inhalation. a) True b) False RATIONALE: Mercury is the only metal that is liquid at room temperature, is easily vapourized, and is well absorbed through inhalation. 24. Lead dust is easily transported in hair and clothing to a worker’s home. a) True b) False RATIONALE: If lead is present in a material that a worker is grinding, sanding or cutting, then airborne lead dust can become lodged in a person’s hair, shirt/pant cuffs, and shoe treads. Proper controls must be put in place to prevent lead dust from contaminating other areas.
