CPE 045 (9 & 10) Flashcards
the anticipation, recognition, evaluation, control and prevention of hazards from work that may result in injury, illness, or affect the well-being of workers and the environment.
Industrial Hygiene
Classification of Health Hazards
Physical
Chemical
Biological
Ergonomics
Psychological
may mean conditions that cause legally compensable illnesses or may mean any conditions in the workplace that impair the health of employees.
Occupational Health Hazard
temperature extremes, vibration, defective illumination, noise, radiation
Physical Health Hazard Agents
solvent, gases, vapors, fumes, mists, pesticides
{ inhale }
Chemical Agents
stress, boredom, burnout
Psychological
viruses, bacteria, fungi, parasites, insects
{ injection, ingestion, inhalation }
Biological Agents
excessive standing, improper motions, lifting heavy loads
Lack of Ergonomic Principles
Types of Chemical in Chemical Hazards
Acid & Base, Dust, Heavy Metal, Organic Solvent (paints, thinner)
Hazardous Form in Chemical Hazards
Vapor, Mists, Particulate Matter, Fumes
Chemicals can only become hazardous when they become ____ and in _____
Airborne
Excessive Concentration
is “the science and art devoted to the recognition, evaluation and control of environmental factors or stresses arising in or from the workplace, which may cause sickness, impaired health and well being, or significant discomfort and inefficiency among workers or citizens of the community.”
Industrial hygiene
are substances in gaseous state are airborne at room temperature. Examples are chlorine, hydrogen sulfide, ammonia, carbon monoxide, sulfur dioxide, phosgene and formaldehyde.
Gases
results when substances that are liquid at room temperature evaporate. Examples are the components of organic solvents such as benzene, toluene, acetone, and xylene
Vapour
is a fine particle of a liquid float in air (particle size of 50 to 100 mμ approximately. Examples: nitric acid and sulfuric acid
Mist
is a solid harmful substance, sometimes ground, cut or crushed by mechanical actions and fine particles float in air (particle size of about 1 to 150 mμ). Examples are metal dusts and asbestos.
Dust
Fume is a gas (such as metal vapor) condensed in air, chemically changed and becomes fine solid particles which float in air (particles size of about 0.1 to 1 mμ). Examples are oxides generated from molten metal such as cadmium oxide, beryllium oxide, etc.
Fume
Methods of Recognizing occupational health stresses/hazards
- Walk-through/ocular inspection
- Review of the process involved
- Knowing the raw materials, by-products and finished products
- Gathering workers’ complaints
- Safety Data Sheet (SDS)
this is necessary in identifying the potential hazards and determining the critical conditions in the workplace. It will be good to make a checklist for inspection.
Walk-through/ocular inspection
The identity of the chemical intermediates formed in the course of an industrial process and the toxicological properties of these intermediates may be difficult to establish.
Review of the process involved
Knowing about the raw materials used and the nature of the products manufactured will help you determine the specific contaminants to which workers are actually exposed.
Knowing the raw materials, by-products and finished products
the actual chemicals or substances handled may be determined by interviewing the workers. More so, their complaints can also be gathered and assessed in the clinic record.
Gathering workers’ complaints
is a summary of important health, safety and toxicological information on the chemical or the mixture ingredients.
Safety Data Sheet (SDS)
the measurement of a particular employee’s exposure to airborne contaminants
Personal Monitoring
