Section 3 - HAZARDS IDENTIFICATION 

Emergency Overview: This material is a low boiling point (115o

F), nonflammable colorless liquid with a 

slight distinctive odor. Toxic if inhaled or swallowed. Contact may cause severe eye 

irritation. Prolonged or repeated exposure to vapors may cause headache, dizziness, 

and drowsiness. Toxic combustion products may be released under fire conditions. 

Potential Health Effects From Overexposure: Possible routes of entry include skin & eye contact and process vapor or 

mist inhalation. 

This is an experimental product whose health effects, physical hazards, and toxicological properties have not been thoroughly 

investigated. 

May be fatal if inhaled, absorbed through skin, or swallowed. Contact with liquid, vapors, or mists may cause severe eye 

irritation. Processing under conditions of inadequate ventilation may produce symptoms of nausea, dizziness, or headaches. 

Exposure to vapors or mists may cause shortness of breath, lethargy, narcosis, unconsciousness, and possible cardiac 

arrhythmias. Prolonged or repeated exposure maybe toxic if inhaled or absorbed through the skin. Prolonged or repeated 

inhalation of vapors may cause lung, liver, heart, kidney, and reproductive effects based on animal data of a chemically 

related substance, Octofluorocyclopentene (C5F8). 

Appropriate precautions should be taken to minimize potential exposure to accidental ingestion, inhalation of process vapors 

or mists, and skin contact. 

It may be possible under certain processing and handling conditions, e.g. processes that create vapors or mists to release this

product in airborne concentrations in excess of the recommended exposure limits or guidelines. Customers and processors 

should do sufficient in-house industrial hygiene monitoring to assure compliance of their operations. In addition, customers 

and processors should confirm that the ACGIH Biological Exposure Index for fluoride is not exceeded in workers using this 

product. 

Overexposure to decomposition or combustion products may cause irritation of the eyes, skin, and respiratory tract. 

Symptoms such as coughing, tearing, and irritation should be regarded as potentially hazardous and measures taken to avoid 

exposure. See Section 10 for information on combustion products. 

Section 4 - FIRST AID MEASURES 

If irritation occurs or persists from any route of exposure, remove the affected individual from the area and seek medical 

assistance. 

Ingestion: Seek immediate medical attention. Consult with medical professionals regarding inducing vomiting to remove 

liquid from stomach. 

Eye Contact: Flush eyes with running water for several minutes while holding eyelids open. Consult a physician if 

irritation persists. 

Skin Contact: Remove contaminated clothing. Wash contact area with soap and water for 15 minutes. Seek medical 

attention if irritation / allergic skin reaction develops. 

Vapor Inhalation: Remove the affected individual to fresh air. Seek immediate medical attention. If breathing has stopped, 

administer artificial respiration. 

Section 5 - FIRE FIGHTING MEASURES

This material is nonflammable. 

Extinguishing Media: Carbon dioxide or dry chemical is recommended for small fires. For large fires use aqueous foam or 

water spray. 
Experimental Product SSY-38 Page 3 

Special Firefighting Procedures: Wear positive pressure self-contained breathing apparatus (SCBA) during the attack 

phase of firefighting operations and during cleanup in enclosed or poorly ventilated areas immediately after a fire. Personnel

not having suitable respiratory protection must leave the area to prevent significant exposure to toxic combustion gases from 

any source. 

Unusual Fire and Explosion Hazards: Low boiling nonflammable liquid. Closed containers may rupture due to pressure 

buildup under fire conditions. Toxic gases may be formed upon combustion and represents a hazard to firefighters. See 

Section 10 for additional information on combustion products. 

Section 6 - ACCIDENTAL RELEASE MEASURES 

Isolate area around spill to prevent exposure to the chemical. Wear respiratory protection and appropriate protective 

equipment to prevent skin and eye contact. Contain spill, ventilate area, and recover as much as possible for disposal. 

Absorb remaining residue with inert material and place into closed containers to await disposal. Wash spill area with soap 

and water. Do not allow product to enter municipal sewers or waterways. 

 

Section 7 - HANDLING AND STORAGE 

Local and spot ventilation should be used to keep concentrations of the chemical below suggested workplace exposure limits 

(AEL). Direct ventilation exhaust away from other work areas. Avoid breathing this material in any form (gas, mist, vapor, 

or fume). Avoid contact with eyes, skin, and clothing. Store in a well ventilated location. Keep container closed when not in 

use. Wash thoroughly after handling, especially before eating, smoking, or using toilet facilities. Do not use or consume 

food in processing areas. 

Section 8 - EXPOSURE CONTROLS/PERSONAL PROTECTION 

Ventilation: Control airborne concentrations below the recommended exposure limits. Use only with adequate ventilation. 

Mechanical ventilation is recommended. Provide local exhaust ventilation to minimize exposure to vapors. Toxic 

concentrations may exist in areas with poor ventilation. 

Respiratory Protection: For protection against process vapors or mists, wear a NIOSH approved respirator suitable for the 

anticipated airborne concentration. Wear a positive pressure air-supplied respirator in situations where there may be potential 

for elevated airborne exposure. 

Protective Equipment: During processing operations, safety goggles or safety glasses with face shield suitable for keeping 

liquid material out of the eyes should be worn when eye contact is anticipated. Rubber gloves and apron should be worn 

when skin contact is anticipated. Provide an eye wash facility and safety shower. 

Respiratory protection and other personal protective equipment are strongly recommended during the following operations: 

gas cylinder exchange / replacement and cleaning or maintenance of dry-etching / chemical deposition devices, attachments, 

connections, or lines.
