Industrial hygiene is basically about the anticipation, recognition, evaluation and control of environment conditions that may have adverse effects. |
|
Industrial hygiene requires multidisciplinary approach and its classical steps are: |
|
- Recognition of possible health hazard in the work area.
- Evaluation of hazards : It is process of assessing exposure and concluding level of risk to the human health
- Prevention and Control of hazards. It is the process of developing and implementing strategies to eliminate or reduce the harmful agents to an acceptable level.
|
|
The practice of industrial hygiene is concern with 3-kinds of situations: |
|
- Initial studies to assess worker’s exposure.
- Follow-Up monitoring.
- Exposure Assessment for epidemiological study.
|
|
ANTICIPATION and RECOGNITION:
|
|
How will you anticipate and recognize the problems? |
- Observe the workplace
- Investigate complaints workers
- Examine accident and near-miss records.
- Examine sickness records
- Interact with workers about their health and safety problems
|
|
EVALUATION
|
|
It is aim to determine how much, how long and how often the workers have been exposed to hazardous agent. |
|
It is process a process of quantifying: |
- Concentration of the agents in the environment
- Duration of exposure
- Level of exposure
|
|
It provides information to: |
- Decide whether intervention is required.
- Design or to test efficiency of control measures.
- Use check-list to help you inspect your workplace.
- Learn the results of inspection done.
|
|
Control Measures
|
|
Primary goal of industrial hygiene is implementation of appropriate and control measures in the workplace. |
|
There are five major ways of control measures: |
- Elimination
- Substitution
- Engineering control
- Administrative controls
- Personal Protective Equipment (PPE)
|
|
STANDARDS FOLLOW FOR INDUSTRIAL HYGIENE MONITORING:
|
|
- OSHA- Occupational Safety and Health Administration
- NIOSH –National Institute of Occupational Safety and Health
- ACGIH- American Conference of Governmental Industrial Hygienist
- The Factories Act, 1947
- The Gujarat Factories Rules, 1963
|
|
QUALITATIVE EXPOSURE ASSESSMENT (QLEA)
|
|
Evaluation of potential personal exposure to workplace chemicals, physical, radiological, and/or biological agents is based on personal experience and professional judgement |
|
Purpose of Qualitative Exposure Assessment |
- Assess and managing occupational exposures to chemical, physical, radiological, and biochemical agent
- Use of a systematic, repeatable assessment approach involving a knowledgeable team.
- Making best use of resources (people, time & finances). I.e. Target areas or tasks of greater risk for training, planning, & budgeting.
|

CONTAINMENT VERIFICATION AND VALIDATION ASSESSMENTS: |
- Our industrial hygiene team has gained extensive experience with containment verification and validation assessments;
- Containment performance testing (CPT), Factory Acceptance Tests (FATs), and Site Acceptance Tests (SATs).
- These assessments are usually carried out using nonhazardous surrogate testing materials or a less potent substitute to establish safe handling guidelines.
