Industrial Hygiene Services

During work, employees gets exposed to different types of Health Hazards.

Protecting employees from adverse health effects due to chemical, biological and physical health hazards is very important in business as it is directly related to productivity, regulatory compliance & health of people.

We offer following services in Industrial hygiene.

  • Workplace Monitoring (Chemical Exposure and Risk Assessment)
  • Ergonomics Study
  • Illumination Survey
  • Noise Monitoring & Mapping
  • Health Hygiene & Safety Audit
  • Vibration Survey
  • Ventilation Survey
  • Indoor Air Quality
  • Hazardous Substance Survey
  • Whole Body Vibration
  • ACM Survey (Asbestos Containing Materials)
  • Industrial Hygiene Training Program

Workplace Monitoring (Chemical Exposure and Risk Assessment)

Workers face a number of potential hazards at work on a daily basis. Airborne hazards such as respirable dusts, gases, and vapors from highly toxic substances are derived from workplace processes such as welding, chemical manufacture, chemical transferring, loading or unloading etc.

Why Undertake Workplace Exposure Monitoring?

Workplace Monitoring must be carried out to determine if the concentration of a substance hazardous to health at the workplace exceeds the relevant prescribed exposure limits set by Factory Act -1948, NIOSH & ACGIH in term of TWA or STEL.

Ergonomics Study


Ergonomics is the scientific study of people at work. The goal of ergonomics is to reduce stress and eliminate injuries and disorders associated with the overuse of muscles, bad posture, and repeated tasks.

Ergonomics study is a study of interaction between Man, Machine and Job which includes the Industrial and Human factors.

  • Industrial factors: mainly focus on physical aspects of work, environmental stressors such as heat, noise, illumination, vibration etc.
  • Human factors:  focus on man-machine relationship. It mainly includes person’s interaction with equipment, machine, workplace and surrounding environment, and also covers human physiology and strength capabilities related to workplace and equipment design.

Illumination Survey

The study evaluates very systematic and crucial lighting installations in the facility which can cause health and safety concerns of the facility due to poor or wrong lighting utilization.

Some common issues arising due to   improper or unhealthy lightning are as follows:

  1. Insufficient illumination
  2. Glare
  3. Color effects
  4. Flicker

Indoor Air Quality

  • Detect common pollutants
  • Environmental evaluation
  • Issues related to odors, irritants, disease or other air quality effects

Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants.

Heath problems due to poor air quality (Both indoor & outdoor)

  • Nausea
  • Headaches
  • Sore throats
  • Skin Irritation
  • Respiratory problems
  • Frequent colds
  • Chronic cough
  • Eye irritation,
  • Lethargy
  • Dizziness
  • Memory lapses

Air is life and fresh air is the first need for survival of living creatures. Absence of air brings death within a few minutes.

Fresh air is essential for life and impacts the entire health and well-being of the individual.

Therefore good ventilation giving sufficient fresh air is a permanent requirement.

Effects of Good Ventilation:-

  1. Availability of sufficient fresh air for breathing
  2. Minimizes oxygen deficiency from the confined space
  3. Removal or dilution of carbon dioxide and other air pollutants
  4. Reduction of body odor and bad smell from the room
  5. Helps in evaporating sweat from the body post heavy physical work
  6. Decreases discomfort and distress
  7. Maintains efficiency of work
  8. Decreases chances of accidents and maintaining safety and productivity.
  9. Provides better job satisfaction and good attitude.

Effects of Ineffective Ventilation:-

  1. Non availability of fresh air
  2. Insufficient air changes
  3. No cooling effects, discomfort, body stress
  4. No removal of air contaminants, body odor, foul smell
  5. Increasing chances of accidents
  6. Lowering efficiency and productivity
  7. No job satisfaction

Heat Stress

Heat Stress Assessment is intended to evaluate and quantify the level of heat, the shop floor workers are exposed to. This is done through identifying the radiant heat, the temperature, humidity and Air velocity.

Heat Related Illness

The terms heat stress and heat strain represent the relationship and difference between external factors and the body's core temperature control mechanisms:

  • Heat Stress
  • Heat Strain
  • Heat Stroke
  • Heat Exhaustion
  • Heat Cramps
  • Heat Rash

Whole Body Vibration

Whole body vibration (WBV) is a generic term used when vibrations (mechanical oscillations) of any frequency are transferred to the human body. Humans are exposed to vibration through a contact surface that is in a mechanical vibrating state. Humans are generally exposed to many different forms of vibration in their daily lives.
