OSEH's specialized program areas lead the University safety effort and support through partnership, guidance, and education to promote health, safety, protection and enhancement of the environment, and regulatory compliance.

Safety Training
Federal law requires that all employees who work in or enter laboratory rooms receive basic safety training. Students attending classes, who are not employees, are exempt from this requirement. Also, if you only work in an office, or computer "lab" and never enter other labs or the loading dock or machine shop, you are not required to attend the safety training. This Comprehensive Lab Safety Training is provided by UM OSEH.

Go to the OSEH Safety Training Website Select quick link on left of screen to determine the kind of safety training you need to take and register for an on-line course. You are required to pass the tests at the end of the training and provide documentation to EMAL staff then you have completed the training. You should be famiiar with basic laboratory safety, radiation hazards, compressed gas handling, liquified gas handling and vacumm systems.

Read the COE and OSEH expectations for conducting safe research

Accidents and Injuries
In case of an accident or injury there is required reporting, see In addition, a copy of any accident report, medical form and any other related documents must be given to Bev Clampit the EMAL Administrator (North Campus incidents) or Carl Henderson the Central Campus Labporatory Manager (Central Campus incidents). The EMAL Safety Committee must receive a copy of the incident report.

Equipment & Standard Operating Proceedures

Equipment Handbooks
There are equipment handbooks for EMAL instruments and these serve as reduced instruction manuals and standard operating proceedure guides. The are all available in PDF format.

Standard Operating Proceedures
Other standard oerating proceedures for gas, chemical handling, etc are also availabel in PDF format.


Material Safety Data Sheets
Material Safety Data Sheets for chemicals show safe handling recommendations, permissible exposure limits, first aid, etc. see or the OSEH website

Chemical Inventories
Chemical inventories are posted on the doors of all EMAL labs and office that contain significant quantities of chemicals so that they are available to OSEH and emergency responders.

Special Note on HF (Hydrofluoric Acid)
EMAL does not permit the presence, use or storage of hydrofluoric acid in any EMAL location. This acid is very dangerous and requires careful handling. Please do not bring HF to EMAL.

Chemical Waste
Chemical solutions may not be poured down drains - Waste must be collected and disposed properly see EMAL has waste solvent and other chemical bottles in the sample preparation areas. Do NOT mix incompatible chemicals, if you are ncertain about compatibility ask an EMAL staff member.
