This concentration should be compared against permissible exposure limits estabhshed by OSHA (Occupational Safety and Health Act) and allowable discharges limits set by federal (EPA) and local emissions regulations.

The amount of ventilation required, like the amount of lighting, depends upon the circumstances. Some general rules are given in Table 8-8.44,45 Note that there are several guidelines and that in some instances more than one may apply. When this occurs the requirements for each should be calculated and the maximum rate used. None of these guidelines applies to hazardous areas, where the air may have to be moved more rapidly. Some estimates are given in Table 8-9. Safety guidelines and OSHA (Occupational Safety and Health Act) rules should be consulted under these conditions.

Many of the chemicals and much of the equipment used in laboratories are potentially hazardous. It is essential that these hazards are clearly identified and appropriate working procedures defined together with adequate training of staff and readily available facilities to deal with the effects of any possible accident. These aspects of laboratory work are covered in the UK by COSHH (Control of Substances Hazardous to Health) Regulations and by OSHA (Occupational Safety and Health Administration) in the USA.
