Environmental chambers where evacuation or other alarms cannot be heard should be equipped with strobe lighting or additional alarms. Central vacuum systems should not be used, since they are vulnerable to contamination. Local vacuum pumps are preferable. All vacuum lines should have cold traps or filters to prevent contamination. Chilled water loops should be available for equipment in need of cooling.
Loops help to avoid excessive wastewater.
Laser laboratories should have an emergency cut-off switch installed near the entrance of the laboratory to turn off the laser remotely. H. Other Laboratories using highly toxic gases should be equipped with alarmed vapor sensors, preferably with automatic shutdown systems. Gas lines from highly toxic gases should use coaxial tubing for double containment. Animal care and use areas must meet Association for Assessment and Accreditation of Laboratory Animal Care International standards.
