OSHA Regulatory Status: This material is classified as hazardous under OSHA regulations.

Emergency Overview:

Simple Asphyxiant-This product does not contain oxygen and may cause asphyxia if released in a confined area. Colorless, non­flammable gas with a possible faint sweetish odor. High concentrations may cause nausea, dizziness and headaches. Repeated or
prolonged skin contact may cause irritation or dermatitis. Use only with adequate ventilation. Contents under pressure. Use and store
below 125OF (52OC).

First Aid Measures

Health Effects:

Carcinogenicity: NTP: No IARC: No OSHA: No

Eye Effects:

May cause minor irritation. Contact with rapidly expanding gas near the point of release may cause frostbite.

Skin Effects:

Liquid R-404A can cause a defatting action on the skin. Prolonged or repeated contact may tend to dry and defat skin causing
irritation and dermatitis. Contact with rapidly expanding gas near the point of release may cause frostbite with redness, skin color
change to gray or white, and blistering.

Ingestion Effects:

None known. Ingestion is unlikely as product is a gas at room temperature.

Inhalation Effects:

High concentrations of R-404A vapors may cause cardiac arrhythmia. Large releases of this product may displace atmospheric
oxygen resulting in asphyxiation. Symptoms of asphyxiation include loss of coordination, increased pulse rate and deeper
respiration.

Medical Conditions Aggravated by Exposure: None known.

Health: 0 Health: 0 0: No Hazard
Flammability: 0 Flammability: 0 1: Slight Hazard

4: Severe Hazard

Ratings were assigned in accordance with Compressed Gas Association (CGA) guidelines as published in CGA Pamphlet P-19 2009
CGA Recommended Hazard Ratings for Compressed Gases, 3rd Edition.

Eyes:

Flush eyes with water for 15 minutes. If irritation persists or frostbite occurs, seek medical attention.

Skin:

Rinse skin thoroughly with water. For skin, immerse skin in lukewarm water. DO NOT USE HOT WATER. For frostbite or
persistent irritation, seek medical attention.

Ingestion:

None required. Product is a gas at normal temperatures and conditions.

Inhalation:

PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE. RESCUE PERSONNEL
SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS. Victims should be assisted to an
uncontaminated area and inhale fresh air. Quick removal from the contaminated area is most important. Unconscious persons should
be moved to an uncontaminated area, and if breathing has stopped, administer artificial resuscitation and supplemental oxygen.
Further treatment should be symptomatic and supportive.
