Proper maintenance is essential to the safety of your laboratory environment, and protects your investment over the long term by preventing erosive chemicals from damaging expensive equipment and furniture. OSHA Standard 29 CFR 1910.1450 requires a Chemicals Hygiene Plan (CHP) for all laboratory facilities, including a performance certification of the fume hood system. LCS can provide this certification for you. LCS offers a complete maintenance program, including preventative maintenance, for fume hood exhaust systems; our comprehensive, three-step program will ensure your fume hood systems operate, and will continue to operate, at recommended performance levels.
