Abstract
In 1985 the Health and Safety Executive set a gravimetric Control Limit for airborne Man-Made Mineral Fibre and in 1987 a respirable fibre number Recommended Limit for Superfine MMMF. A limited investigation was carried out of the use of glass and ceramic fibre products used as protection against welding 'batter' and oxyacetylene welding flame. Airborne fibre levels are compared with the Occupational Exposure Limits.
摘要
1985年，健康与安全执行委员会设定了空气中人造矿物纤维的重量控制限值，1987年又设定了超细人造矿物棉的可吸入纤维数量推荐限值。对用作防护焊接“熔渣”和氧乙炔焊火焰的玻璃和陶瓷纤维产品的使用情况进行了有限的调查。将空气中纤维水平与职业接触限值进行了比较。
