13.4 Members of any on-site responding organization

(such as emergency response teams (ERTs)) should be

trained on the use of the emergency response plan, and

all other procedures for which they are designated

responders.

13.4.1 Responders should not perform actions for

which they have not been trained.

13.4.2 If on-site responders are not provided, facility

operators should make provisions according to the

regulations for the location and should notify all

supplier employers about the extents and limits of such

response provisions.

NOTE 40: Some jurisdictions require trained on-site

responders at each facility. Other jurisdictions specify that

only local authorities (e.g., fire departments, hazardous

materials units, police) can respond to emergency situations.

Certain jurisdictions allow employers to choose whether they

train their employees to respond to emergencies or if they will

depend upon local authorities for emergency response. Each

employer should understand the requirements of each specific

jurisdiction in which they will perform work.

13.4.2.1 An example of an organization that offers

emergency medical training and certification is the Red

Cross.

spontaneously upon contact

with air

Fire, explosion Silane, phosphine

Poisons

Any substance that produces a

harmful effect when

introduced to the body

Serious illness or death Phosphine, diborane, arsine

Inert Gas

reducing agents

Violent reactions when mixed

with other chemicals; can

enhance fire

Nitric acid, hydrogen peroxide,

nitrous oxide

Irritants

Corrosives, solvents, oxidizers

(effects depend on

concentration)

hydrogen peroxide, acetone

Sensitizers

Any substance that can illicit

an allergic reaction

Effects range from mild skin or

respiratory reactions to

anaphylactic shock and death

“R” indicates “Recommended”.

Note 1: Goggles and respirator should be worn if the sources are not isolated or exhausted, and are of a nature that they could enter the eye or be

inhaled.

Note 2: Gloves should be used if radioactive sources that are not sealed are being handled.

Note 3: Protective filters should be considered for long-term viewing (> 10 seconds). Where visible light doesn’t elicit the aversion response.
