A material safety data sheet (MSDS) is a form containing data regarding the properties of a particular substance. An important component of product stewardship and workplace safety, it is intended to provide workers and emergency personnel with procedures for handling or working with that substance in a safe manner, and includes information such as physical data (melting point, boiling point, flash point, etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, and spill handling procedures. MSDS information may include instructions for the safe use and potential hazards associated with a particular material or product. MSDS can be found anywhere chemicals are being used.

Material Safety Data Sheet: Hydrogen
Formula : H2

Principal Hazards:
Hydrogen is very flammable. It forms a potentially explosive mixture with air over a wide composition range (4% - 75% hydrogen by volume).

Safe Handling:
Wear safety glasses. Work in a well ventilated area, preferably using a fume cupboard. Remove any source of ignition, such as naked flames or hot air guns, from the working area before starting. If hydrogen is being moved through the area in balloons, watch out for sources of ignition. Be aware that hydrogen may be ignited by static electricity.

Emergency
Eye Contact : Unlikely to occur
Skin Contact : Unlikely to occur
If inhaled : Hydrogen is not poisonous, but is an asphyxiant. Accidental inhalation of sufficient hydrogen to cause breathing problems is unlikely, but if it occurs, remove the patient to fresh air. If breathing has stopped, immediately start artificial respiration and call for medical help.

Disposal
Small amounts of hydrogen can be allowed to disperse naturally, preferably through a fume cupboard.

Protective Equipment
Wear safety glasses because of the risk of fire or explosion.
