3.Behave in a manner that will ensure the health and safety of everyone in the building.
4.Wear splash-proof chemical goggles over my eyes at all times when working with chemicals and/or equipment, as well as wear any hand, body and clothing protective equipment.
5.Know the location and use of first aid equipment, the eye wash station and fire extinguishing equipment.
6.Refrain from eating, drinking (even water), and chewing gum or apply cosmetics in the lab.

Compressed Gas
A substance that is a gas at normal room temperature and pressure and is contained under pressure.
Hazards: Explosions, toxic, oxygen displacement
Corrosive Material
Corrosive substances can destroy living tissues and materials by contact.
Hazards: burn human tissues
Flammable Material
A material or substance that can catch fire if exposed to a source of ignition.
Hazards: burns, fire
Explosive Material
Explosive materials are reactive substances that contain a great amount of potential energy that can produce an explosion if released suddenly.
Oxidizing Material
Oxidizing materials describe chemicals that can combine with oxygen and other substances, creating rust and further oxides.
Environmental Hazard
Environmental hazards concern hazards that can affect biomes or ecosystems.
Biohazardous Material
Biohazardous materials refer to hazardous biologic materials such as blood products, animal waste, human body fluids, human blood, and so on.
Hazards: Infections, viruses, bacteria, diseases, allergic reactions
Acute Toxicity
Acute toxicity refers to adverse effects that take place after being exposed to toxic chemicals. These effects often occur and appear rapidly after a single or multiple exposures in less than 24 hours.
Symptoms include: Dizziness, nausea, vomiting, chest pain, fainting, and possibly fatal.
Long Term Health Hazard
Long-Term Health Hazard refers to chronic health effects that manifest from long-term exposure to substances that contain toxic properties.
Less Serious Health
Less serious health effects signs are often seen on products that can cause health effects that aren’t as serious.
