INDUSTRIAL HYGIENE Flashcards
(34 cards)
art and science devoted to RECOGNITION, EVALUATION, and CONTROL of environmental stresses arising in or from the workplace, which may cause sickness, impaired health and well-being, or significant discomfort among workers.
industrial hygiene
methods of recognition
• Walk though survey or ocular inspection
• Reviewing process involved
• Knowing the raw materials used
• Gathering of worker’s complaints
evaluation can be performed through
work environment measurement (wem)
Refers to the determination of workplace stresses and their hazardous effects on the worker through direct measurement of hazards using industrial hygiene equipment.
WEM
purpose of WEM
• To determine the magnitude of harmful environmental agents
• To physically check the environment through measurement
• To predict harmfulness of new facilities, raw materials, production process and working methods
• To evaluate effectiveness of environmental control measures adopted to improve the workplace
• To maintain favorable environmental conditions
• TO monitor worker’s exposure to harmful substances
(2) The employer shall carry out the working environment measurement in indoor or other workplaces where hazardous work is performed and shall keep a record of such measurement
Rule 1077.03 in the OSHS
RULE 1077
Working Environment Measurement
sampling and analysis carried out in respect of the atmospheric working environment and other fundamental elements of working environment for the purpose of determining actual conditions therein.
working environment measurement
the rule 1077 shall be effective upon announcement by
Secretary of Labor and Employment
In the event of inability to perform the working environment measurement, the employer shall commission the _______________ and _________________ concerned and other institutions accredited or recognized by the Bureau, to perform the measurement.
Bureau/Center for Occupational Safety; Health/Regional Labor Office
TRUE OR FALSE. The working environment measurement shall be performed periodically as may be necessary but not longer than annually.
TRUE
- It is the measurement of contaminant in the workroom.
This helps pinpoint work areas with high or low exposure level of contaminants
Area/ Environmental Sampling
- It is the measurement of a particular worker’s exposure to hazards or contaminants.
Personal sampling
- It involves the measurement of changes in the composition of bodily fluids, tissue or expired air to determine absorption of potentially hazardous material.
biological sampling
measures illumination level
lux meter
measures noise level
sound level meter
measures level of heat
globe thermometer
measures air direction
smoke tester
measures air movement
anemometer
How is evaluation done to determine the magnitude or level of hazards
Through the use of industrial hygiene equipment
TRUE OR FALSE. The result of the sampling is then compared to the standards and then analyzed if is tolerable or hazardous enough.
TRUE
recommended illumination level at passageway, corridor, and warehouse
min. 50 lux
recommended illumination level at engine and boiler rooms, toilets and washrooms
min. 100 lux
recommended illumination level at canning and preserving; planing of lumber and veneering
200 lux
