Adjustment of occupational exposure limits for seasonal occupations

American Industrial Hygiene Association Journal, 1980
A previously reported model for predicting adjustments to permissible exposure limits has been extended to include adjustments for seasonal occupations. On the basis of the model, no "credit" (i.e., increase in exposure limits) may be allowed for a short work season unless the biological half-life in hours of the agent of concern is greater than 38 W ...

Occupational Exposure Limits For Novel Work Schedules

American Industrial Hygiene Association Journal, 1975
Work schedules other than 7 to 8 hr/day and 40 hr/week are being introduced in many industrial operations. Novel work schedules, such as four 10-hour workdays per week or three 12-hour workdays per week for three weeks followed by four 12-hour workdays for three weeks and several other plans are presently being used. The Threshold Limit Values (TLV) do

Toward WHO-recommended occupational exposure limits

Toxicology Letters, 1995
The WHO Project on Recommended Health-based Limits in Occupational Exposure resulted in the development of occupational exposure limit (OEL) values for a few groups of widely used industrial chemicals. A comparative analysis of the WHO-recommended OEL and existing OEL in selected countries has been made.

Occupational Exposure Limits

2005
Occupational exposure limits (OELs) provide health and safety professionals an important tool for protecting worker health. OELs provide health and safety guidance to chemical users, inform workers of potential adverse effects of chemical exposure, and provide a scientific basis for evaluating whether existing environmental exposure controls are ...

The concept of occupational exposure limits

Science of The Total Environment, 1991
Germany was the first country to introduce occupational exposure limits (OEL) in 1886. A theoretical consideration for the existence of toxicological thresholds has been provided. Prerequisites for OELs are seen in: reversibility, existence of a threshold, deviation of (physiological) functions from normal to be regarded as "safe", knowledge about ...

Adjusting occupational exposure limits for moonlighting, overtime, and environmental exposures

American Industrial Hygiene Association Journal, 1979
A mathematical model is used to predict relative body burdens of inhaled contaminants in workers who work two jobs or overtime, or who experience off-the-job exposure to air contaminants. Expected "peak" or maximum body burdens from multiple exposures are compared to those expected from the "normal" occupational exposure on which TLVs and Permissible ...

Occupational exposure limits—at the crossroads

Occupational and Environmental Medicine, 2010
Setting occupational exposure limits (OELs) for hazards in the workplace has been an integral component of worker health protection programs for many decades. These OELs have been established by many authoritative bodies around the world, such as the Threshold Limit Value Committee (TLV) of the American Conference of Governmental Industrial Hygienists (

Occupational exposure and dose over time: Limitations of cumulative exposure

American Journal of Industrial Medicine, 1992
AbstractCumulative exposure (average intensity times duration) is one of the most common summary measures for exposure used in occupational epidemiology. Its utility for describing quantitative exposure‐effect relationships is based on several interlocking assumptions about the processes relating exposure to tissue dose, and tissue dose to adverse ...

Occupational Exposure Limits in France

1990
A scientific committee gathers experts, personnally appointed by the French Ministry of Labour, and administration representatives. This group critically reviews published data (industrial experience, experimental toxicological data, physicochemical properties, sampling and analysis capabilities, exposure/response relationship), discusses possibilities

Exposure limits and medical surveillance in occupational health

American Journal of Industrial Medicine, 1982
AbstractThe standards for pollutants in workplace air constitute a social consensus or agreement about acceptable levels of occupational hygiene. This agreement to exposures up to these limits inevitably includes a finite risk to the health of the workers.
