Industrial Hygiene


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.
 
 

QUANTITATIVE EXPOSURE ASSESSMENT (QNEA)

 
Chemical Exposure Assessment
  • Workplace / Personal (Dust, fume, solvent, vapour) / Workplace monitoring (GFR 1963,
    Form no. 37)
  • Sample analysis by AIHA-accredited laboratories / NABL-accredited laboratories.
 
 

AREA / PERSONAL NOISE MONITORING

 
  • Area Noise Monitoring
  •  Personal Noise Monitoring
  • Area Noise Mapping
 
 

COMPRESSED BREATHING AIR ANALYSIS AS PER OSHA GRADE-D

 
Parameter to be analyzed:
  • Carbon Monoxide
  • Water Vapour
  • Oil Mist
  • Oxygen
  • Carbon Dioxide
 

WORKPLACE ERGONOMICS ASSESSMENT

 
  • Rapid Upper Limb Assessment (RULA)
  • Rapid Entire Body Assessment (REBA)
  • NIOSH Lifting Methodology
 
 

ILLUMINATION SURVEY (AS PER IS 3646 (PART – I, II) 1992

 
  • Illumination Survey is conducted to identify bright light, glare, lowlight, or flickering light to avoid potential hazards and evaluate risk to improve employee safety
 
 

VIBRATION MONITORING

 
  • Hand Arm Vibration
  • Full Body Vibration
 
 

INDUSTRIAL VENTILATION SURVEY

  • Effectiveness check for Local Exhaust
  • Ventilation / General Ventilation
  • Area air movement monitoring
  • Air Change per Hours Calculation / Form No.26-A
 

HEAT STRESS MONITORING

  • Workload assessments
  • Area[WBGT]heat stress Monitoring
 

INDOOR AIR QUALITY ASSESSMENT

 
Parameter to be analyzed
  • CO2, CO, NOx, Formaldehyde, Temperature, Humidity, O3, O2, PM1, PM2.5 and PM10
 

MICROBIOLOGICAL ASSESSMENT

  • Total Plate Count
  • Total yeast & mould count
  • Swabs Testing
  • Legionella Bacteria
  • Pseudomonas sulfate-reducing bacteria
 
 
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.
