Reviews and Notes: Pathology: Laboratory Biosafety Manual

Laboratory Biosafety Manual Second edition. 133 pages. Geneva, Switzerland: World Health Organization; 1993. $23.40. Safe laboratory techniques for constructing laboratories and for containing hazardous substances to protect the workers and the environment are now a defined science. This book considers the aspects of designing laboratories that handle materials that may be hazardous to both workers and the environment. Biosafety hazards are graded from level 1 to level 4, with level 4 requiring maximum containment. (For example, level 4 laboratories must set tick and mite cages into trays of oil that serve as moats against the inadvertent exit of the arachnids from their containers.) Readers in the United States should compare recommendations with Occupational Safety and Health Administration requirements. A warning to us all: Circuit breakers do not protect people. They are intended to protect equipment. It is grounding that protects people from electric shock.
