Exposure limits maximum

In accordance with demonstrated differences between the various asbestos fiber types, the workplace regulation in many countries specifies different exposure limits for chrysotile and the amphiboles (45). Moreover, to alleviate estabHshed, or apprehended, risk from substitute fibers, the regulation often specifies maximum exposure limits for synthetic fibers (46) values of exposure limits adopted in leading industrial countries are coUected in Table 8. 

MEL, MAXIMUM EXPOSURE LIMIT (uk) The luaximum eoneentration of an airborne substanee (averaged over a referenee period) to whieh employees may be exposed by inlialation under any eueumstanees. (Listed in Oeeupational exposure limits , EH40/-HSE.)... 

In the UK (under the Control of Substanees Hazardous to Health Regulations 1999) there are maximum exposure limits (MEL) and oeeupational exposure standards (OES) ... 

The hazards with glutaraldehyde are those of irritation to the skin, eyes, throat, and lungs. It can cause dermal and respiratory sensitization, resulting in rhinitis and conjunctivitis or asthma. In the UK the Maximum Exposure Limit is just 0.05 ppm (8 hr TWA limit) and 0.05 ppm (15 min STEL) with a Sen notation (p. 93). 

The Occupational Exposure Standards imposed for trichloroethylene are Maximum Exposure Limits of 100 ppm (8 hr TWA) and 150 ppm (15 minute reference period). A skin notation Sk is applicable because of the potential for skin absorption. Because of its volatility, trichloroethylene is not recommended for cold cleaning it is normally used in partially enclosed vapour degreasing equipment provided with local exhaust ventilation. 

In the UK vinyl chloride is also subject to an overriding annual maximum exposure limit of 3 ppm.

Long-term exposure limit (LTEL) An exposure limit requirement based on the assumption that the total body intake of a pollutant below this limit over an 8-hour working day will have no harmful effect on the worker over a working life. See also Maximum exposure limit (MEL), Occupational exposure limit (OEL), and Short-term exposure limit (STEL). 

Maximum exposure limit (MEL) The maximum concentration of an airborne substance, averaged out over a reference period to which employees may be exposed by inhalation. 

Maximum Exposure Limit MEL) Maximum limits of concentration of airborne toxic contaminants, listed by the Health and Safety Executive which must not be exceeded. 

Maximum exposure limit (MEL) — the maximum concentration of an airborne substance, averaged over a reference period, to which employees may be exposed by inhalation under any circumstance. Thus, exposure to a chemical assigned an MEL must be as low as is reasonably practicable and, in any case, below the MEL. 

The HAZWOPER was developed to protect the health and safety of workers engaged in operations at hazardous waste sites, hazardous waste treatment facilities, and emergency response locations. HAZWOPER covers issues such as training, medical surveillance, and maximum exposure limits. 

Maximum Exposure Limit. See Occupational Exposure Limits. 

In the UK a list of occupational exposure limits is published by the HSE in Guidance Note EH40, which is updated annually. There are two kinds of occupational exposure limits maximum exposure limits (MELs) and occupational exposure standards (OESs). For substances which have been assigned a MEL, the level of exposure should be reduced so far as is reasonably practicable and in any case should not exceed the MEL. For substances which have been assigned... 

Rubber process dust is dust arising in the stages of mbber manufacture where ingredients are handled, weighed, added to or mixed with uncured material or synthetic elastomers. The aggregated maximum exposure limit in the UK is 6 mg/m3 (EH40/2000). The exception is chemicals for which specific exposure limits exist. 

A revised list of maximum exposure limits (MEL), and occupational exposure standards (OES), has been approved by HSC with the exception of dichloromethane, which will remain a maximum exposure limit pending further discussions. Tabulated data are presented of changes to occupational exposure limits with details of new MELs, new OESs, revised OESs, and withdrawn OESs. EUROPEAN COMMUNITY EUROPEAN UNION UK WESTERN EUROPE... 

For occupational exposure to chemicals as opposed to environmental exposure, other parameters such as threshold limit values (or maximum exposure limits) are determined in a similar way and are based on exposure for an eight-hour working day. 

There is no listed threshold limit value or maximum exposure limit for the pigment. Normal practice is to consider it a nuisance dust with TLV 10 mg/m3. The pigment is not listed as a dangerous substance in the EC nor in any similar national or international classification neither is it classified as hazardous for disposal.
