Summary
Asbestos removal work, while requiring protective gear, induces moderate physiological strain. Workers experienced elevated heart rates and temperatures, with poor postures common during tasks.
Area of Science:
- Occupational Health
- Environmental Science
- Human Physiology
Background:
- Asbestos removal necessitates protective clothing and respirators to mitigate dust exposure.
- Understanding the physiological impact on workers is crucial for safety protocols.
Purpose of the Study:
- To measure physiological responses of asbestos workers in real work environments.
- To assess the impact of different protective equipment and work postures on worker strain.
Main Methods:
- Eight asbestos workers were monitored for heart rate, skin, and rectal temperatures.
- Environmental parameters, work postures, and subjective ratings were recorded.
- Oxygen consumption and sweat rates were calculated and measured.
Main Results:
- Mean heart rate ranged from 101-141 bpm, with oxygen consumption at 27%-60% of maximal.
- Peak rectal temperature reached 37.7°C, and sweat rates varied from 162-583 g/h.
- Poor work postures, including elevated arms, were frequent, contributing to physiological strain.
Conclusions:
- Asbestos removal imposes moderate physiological strain, with occasional heavy loads.
- Protective clothing and respirators are essential, but work postures also significantly influence strain.
- Further research into optimizing work methods and equipment is warranted.

01:20Personal Protective Equipment
Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:
01:22PPE Use in Healthcare Settings I: Donning
Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...
01:10PPE Use in Healthcare Settings II: Doffing
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.
01:26Standard Precaution
Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.

01:28Survey Safety
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...
