Laboratory Safety

Disposing of equipment? See the Equipment Disposal and Relocation form.

Compressed gas safety: All compressed gasses can be dangerous, even those that are not flammable or toxic. Inert gasses act as asphyxiants, and a ruptured cylinder can cause physical damage. (See the Airgas cylinder safety sheet.) Cryogenic liquids pose the same asphyxiation hazard as compressed gasses, but also introduce the possibility of severe cold burns.

For information on disposing of chemical, biological, radioactive, or other hazardous waste, see our waste page.

See our guide on Labels and Warnings in the laboratory.

Inspection guidelines

Personal Protective Equipment

Proper selection and use of PPE is important! See our glove page, eye protection page, lab coat/scrubs page, and respirator page.


There are three types of hoods in use at Case: fume hoods, laminar flow hoods, and biological safety cabinets. Fume hoods and biological safety cabinets are an enginering control to protect personnel from hazardous fumes and biohadardous agents. (Report chemical fume hood issues on our online form. Biological safety cabinets and lamainar flow hoods are certified by LCS through a separate form.) Laminar flowhoods protect materials from contamination. Like fume hoods, biological safety cabinets provide protection for personnel, but focusing on biological rather than chemical agents. Class II and III biological safety cabinets also provide product protection.

Is your fume hood being repaired? See the hood status (xls).
