NUR 2349 Discussion Common Hazards

Take some time to research the many hazards that you will face as you take care of your patient. Describe one hazard that could harm you and/or you patient in the healthcare setting. What actions can nurses take to prevent harm to your patient or self?

What is risk?

Risk is the chance or probability that a person will be harmed or experience an adverse health effect if exposed to a hazard. It may also apply to situations with property or equipment loss, or harmful effects on the environment.

For example: the risk of developing cancer from smoking cigarettes could be expressed as:

  • “cigarette smokers are 12 times (for example) more likely to die of lung cancer than non-smokers”, or
  • “the number per 100,000 smokers who will develop lung cancer” (actual number depends on factors such as their age and how many years they have been smoking).

These risks are expressed as a probability or likelihood of developing a disease or getting injured, whereas hazard refers to the agent responsible (i.e. smoking).

Factors that influence the degree or likelihood of risk are:

  • the nature of the exposure: how much a person is exposed to a hazardous thing or condition (e.g., several times a day or once a year),
  • how the person is exposed (e.g., breathing in a vapour, skin contact), and
  • the severity of the effect. For example, one substance may cause skin cancer, while another may cause skin irritation. Cancer is a much more serious effect than irritation.

What is a risk assessment?

Risk assessment is the process where you:

  • Identify hazards and risk factors that have the potential to cause harm (hazard identification).
  • Analyze and evaluate the risk associated with that hazard (risk analysis, and risk evaluation).
  • Determine appropriate ways to eliminate the hazard, or control the risk when the hazard cannot be eliminated (risk control).

The OSH Answers document on Risk Assessment has details on how to conduct an assessment and establish priorities.

Are there other terms used to describe these processes?

It is common to see the process of identifying hazards and assessing the corresponding risk to be described in various ways, including “hazard assessment”, “hazard and risk assessment”, “all hazards risk assessment”, etc.

Regardless of the terminology used, the critical steps are to make sure the workplace has taken a systematic approach that looks for any hazards (existing or potential), has take appropriate steps to determine the level of risk of these hazards, and then taken measures to control the risk or eliminate the hazard.

Documentation from CCOHS will use the terms “hazard identification ” and “risk assessment ” to describe the process of first looking for hazards, then determining the level of risk from that hazard. Hazard control describes the steps that can be taken to protect workers and the workplace.

What is an adverse health effect?

A general definition of adverse health effect is “any change in body function or the structures of cells that can lead to disease or health problems”.

Adverse health effects include:

  • bodily injury,
  • disease,
  • change in the way the body functions, grows, or develops,
  • effects on a developing fetus (teratogenic effects, fetotoxic effects),
  • effects on children, grandchildren, etc. (inheritable genetic effects)
  • decrease in life span,
  • change in mental condition resulting from stress, traumatic experiences, exposure to solvents, and so on, and
  • effects on the ability to accommodate additional stress.

Will exposure to hazards in the workplace always cause injury, illness or other adverse health effects?

Not necessarily. To answer this question, you need to know:

  • what hazards are present,
  • how a person is exposed (route of exposure, as well as how often and how much exposure occurred),
  • what kind of effect could result from the specific exposure a person experienced,
  • the risk (or likelihood) that exposure to a hazardous thing or condition would cause an injury, or disease or some incidence causing damage, and
  • how severe would the damage, injury or harm (adverse health effect) be from the exposure.

The effects can be acute, meaning that the injury or harm can occur or be felt as soon as a person comes in contact with the hazardous agent (e.g., a splash of acid in a person’s eyes). Some responses may be chronic (delayed). For example, exposure to poison ivy may cause red swelling on the skin two to six hours after contact with the plant. On the other hand, longer delays are possible: mesothelioma, a kind of cancer in the lining of the lung cavity, can develop 20 years or more after exposure to asbestos.

Once the hazard is removed or eliminated, the effects may be reversible or irreversible (permanent). For example, a hazard may cause an injury that can heal completely (reversible) or result in an untreatable disease (irreversible).

What types of hazards are there?

A common way to classify hazards is by category:

  • biological – bacteria, viruses, insects, plants, birds, animals, and humans, etc.,
  • chemical – depends on the physical, chemical and toxic properties of the chemical,
  • ergonomic – repetitive movements, improper set up of workstation, etc.,
  • physical – radiation, magnetic fields, pressure extremes (high pressure or vacuum), noise, etc.,
  • psychosocial – stress, violence, etc.,
  • safety – slipping/tripping hazards, inappropriate machine guarding, equipment malfunctions or breakdowns.
