A medical surveillance program is designed to protect the workers health. Given the limitations of industrial hygiene monitoring data and the many hazards involved in hazardous waste activities, medical surveillance data may provide the only indication that worker exposure to toxic substances has occurred. 

LVHV nozzles can create problems that may be sufficiently severe as to prevent their use, usually in the form of ergonomic encumbrances and excessive noise. These problems can be dealt with, to limited extents, and LVHV applications can be effective. It must also be understood that dust control by 1..VHV systems is ultimately limited. No ventilation control measure can ensure sufficient worker protection down to extraordinatily low acceptable dust levels. Worker protection must always be confirmed by industrial hygiene monitoring and evaluation, and administrative control measures such as respiratory protection may be necessary.

One of the most important objectives of any industrial hygiene monitoring program is to accurately interpret air sampling results. The use of statistics in this assessment process is necessary because all measurements of physical properties contain some unavoidable random measurement error. The variation of occupational exposure measurements is an argument for statistical information not against it. (10)(15)... 

The health and environmental data collected in the laboratory becomes the basis for defining operating controls and practices auid for manufacture and use. Typically, the chemical manufacturer, and many users, initiate industrial hygiene monitoring auid medical surveillance programs in the commercial phase.

Industrial Hygiene Monitoring—taking samples in the worker s breathing zone to determine if toxic or hazardous substances are present at unacceptable levels. 

Cyclone As used in industrial-hygiene monitoring, a particle-size selector whose operation is based on imparting sufficient tangential velocities to relatively larger (heavier) particles sufficient to cause impaction on the walls of a conical chamber, while permitting smaller (respirable) particles to remain entrained in the air system. 

Industrial hygiene monitoring should be performed for each nonemergency operation or procedure where a respirator is used, including where respirators are worn forpersonal reasons. Only respirators which are approved and provided by the semiconductormanufacturer, and certified by competent authority (e.g., UK, HSE US, NIOSH or MSHA) should be allowed to be worn by employees.
