Exam 6: Biological and Chemical Agents

What are the types of control measures that can be used to ensure the safe handling of both chemical and low-level biological agents?

An SDS must contain information about composition and ingredients.

Through what physiological system would poison ivy have an effect on gardeners and agricultural workers?

Sensitization is an example of which of the following?

The best method for mitigating the risks associated with chemical and biohazards is substitution.

A chemical's ability to pass through the skin is closely associated with toxicity.

Ciera's is a 55-year-old registered nurse who works in a large hospital. Ciera recently contracted a bacterial infection from a patient. Her treatment was a course of antibiotics. Following her treatment Ciera noticed she had trouble hearing. She visited an audiologist who informed her that her recent hearing loss is likely the result of ototoxicity. Which of the following is most likely the cause of Ciera's hearing loss?

Custodial staff (also known as janitors or cleaners) are the unsung heroes of the workplace. Going about their work while many of us are in bed, they deal with a whole host of situations that bring them into contact with a wide range of chemical and biological agents. They are exposed to residues left in the air and on surfaces from manufacturing processes, from service operations, and from human excretions (sweat, body oils, from sneezing, and so on). While employees of the firms that they service receive training about specific chemical and biological hazards, the custodial staff are often unaware of some of the hazards that they may encounter. -The owner of the cleaning company tries to protect his workers by getting as much information as he can about chemical hazards when meeting with new clients and renewing contracts with existing clients. In general, for what percentage of chemicals will he be provided with toxicity data?

Evan is the OH&S manager for a research lab that has Biosafety Level 1 (BSL 1) organisms. What does he need to do to protect himself from this type of organisms?

Which of the following is most likely to create a synergistic effect with airborne chemicals in a manufacturing plant?

List the seven types of chemical contaminants found in workplaces. Describe an example of one chemical hazard that office workers may be exposed to and one example of a chemical hazard that manufacturing workers may be exposed to. Describe a workplace human resource practice or policy that could address each of these health and safety issues.

List the eight general characteristics and properties that make solvents effective. Pick two of the eight and explain how that characteristic/property would make a solvent hazardous.

Which of the following factors allows a solvent to spread evenly and quickly?

What is the recommended remedy for occupational asthma (e.g. crab asthma experienced by the snow crab workers in Newfoundland)?

Custodial staff (also known as janitors or cleaners) are the unsung heroes of the workplace. Going about their work while many of us are in bed, they deal with a whole host of situations that bring them into contact with a wide range of chemical and biological agents. They are exposed to residues left in the air and on surfaces from manufacturing processes, from service operations, and from human excretions (sweat, body oils, from sneezing, and so on). While employees of the firms that they service receive training about specific chemical and biological hazards, the custodial staff are often unaware of some of the hazards that they may encounter. -Custodial staff are exposed to aerosols through the cleaning products they use and as a by-product of mechanical and human activity at each workplace where they clean. What is the part of the respiratory system that is spiral shaped and could be protected from aerosols by wearing a face mask?

The immediate pain and discoloration you experience after burning your hand on a hot surface is an example of which of the following?

Chris's restaurant in Halifax, Nova Scotia has just received a substandard evaluation from the Ministry of Agriculture's restaurant inspector. The report cited the following problems: dirty conditions in the kitchen, leaking refrigeration units, unclean restrooms, cross-contamination (e.g. cutting raw meat and vegetables without cleaning or replacing the cutting board/knife), and inadequate ventilation in the kitchen. There have been a number of cases of food poisoning in the past six months (staff and customers). The restaurant's negative rating has been posted on an online website available to current and potential customers, so Chris wants to get the problems fixed as soon as possible and have the notice removed. For each problem, identify the form and type of chemical and/or biological hazard involved. Discuss what controls Chris should put in place so that next time around the restaurant will receive a much more positive rating from the inspectors, making special note of new hazards that might arise while he is fixing the problems.

Besides record keeping, what control measure ensures that baseline tests will be available when needed?

A human is an example of a reservoir.
