SECTION 4 FIRST AID MEASURES

Eye Contact

For direct contact, remove contact lenses if present. Immediately hold eyelids apart and flush the affected eye(s)

with clean water for at least 20 minutes. Seek immediate medical attention.

Skin Contact

Remove contaminated shoes and clothing and cleanse affected area(s) thoroughly by washing with mild soap and

water or a waterless hand cleaner. If irritation or redness develops and persists, seek medical attention.

Inhalation

If respiratory symptoms or other symptoms of exposure develop, move victim away from source of exposure and

into fresh air. If breathing difficulties develop, oxygen should be administered by qualified personnel. If victim is

not breathing, clear airway and immediately begin artificial respiration. Seek immediate medical attention.

Ingestion

Call a physician or poison control center immediately. Aspiration hazard: Do not induce vomiting or give anything

by mouth because this material can enter the lungs and cause severe lung damage. If spontaneous vomiting

occurs, lean victim forward to reduce the risk of aspiration and monitor for breathing difficulties. If victim is drowsy

or unconscious, place on the left side with the head down. If possible, do not leave victim unattended and observe

closely for adequacy of breathing. Seek immediate medical attention.

Notes to Physicians

At high concentrations hydrogen sulfide may produce pulmonary edema, respiratory depression, and/or

respiratory paralysis. The first priority in treatment should be the establishment of adequate ventilation and the

administration of 100% oxygen. Nitrite therapy (found in the cyanide antidote kit) has been suggested as a

therapy for hydrogen sulfide exposure. Amyl nitrite is given by inhalation (for 30 seconds every minute until anintravenous line is established) followed by intravenous sodium nitrite (300 mg over absolutely no less than 5

minutes). This may aid recovery by forming sulfmethemoglobin, thus removing sulfide from combination in tissue.

The antidotal efficacy of nitrite therapy is controversial, but is currently recommended if it can be started within the

first few minutes after exposure. Nitrite therapy should not be allowed to interfere with the establishment of

adequate ventilation and oxygenation. (Source: ATSDR Toxic Substances Portal Hydrogen Sulfide).

Exposure Monitoring

Federal regulations (29 CFR 1910.1028) specify medical surveillance programs for certain exposures to benzene

above the action level or PEL (specified in Section (i)(1)(i) of the Standard). In addition, employees exposed in an

emergency situation shall, as described in Section (i)(4)(i), provide a urine sample at the end of the shift for

measurement of urine phenol.

Medical Conditions Aggravated by Exposure

Conditions which may be aggravated by exposure include skin disorders and eye disorders. Exposure to high

concentrations of this material may increase the sensitivity of the heart to certain drugs.

Other Comments

Before attempting rescue, first responders should be alert to the possible presence of hydrogen sulfide, a

poisonous gas, and should consider the need for respiratory protection (see Section 8).

SECTION 5 FIRE FIGHTING MEASURES

NFPA 704 Hazard Class:

Health: 1 (Slight)

Flammability: 1 (Slight)

Instability: 0 (Minimal)

Unusual Fire and Explosion Hazards

This material may burn, but will not ignite readily. Liquid hydrocarbons may be present in sufficient quantity to

create fire hazard. This product will float and can be reignited on surface water. Vapors are heavier than air and

can accumulate in low areas. If container is not properly cooled, it can rupture in the heat of a fire. Hazardous

combustion/decomposition products, including hydrogen sulfide, may be released by this material when exposed

to heat or fire. Use caution and wear protective clothing, including respiratory protection.

Extinguishing Media

Dry chemical, carbon dioxide, or foam and water streams is recommended. Water spray is recommended to cool

or protect exposed materials or structures. Carbon dioxide can displace oxygen; use caution when applying

carbon dioxide in confined spaces. Water alone may be ineffective for extinguishment.

Protection of Firefighters

For fires beyond the initial stage, emergency responders in the immediate hazard area should wear protective

clothing. When the potential chemical hazard is unknown, in enclosed or confined spaces, a self-contained

breathing apparatus should be worn. Wear other appropriate protective equipment as warranted (see Section 8).

Firefighting Procedures

Small fires in the incipient (beginning) stage may typically be extinguished using handheld portable fireextinguishers and other fire fighting equipment. For larger fires, isolate immediate hazard area and keep

unauthorized personnel out. Stop spill/release if it can be done safely. Move undamaged containers from

immediate hazard area if it can be done safely. Water spray may be useful in minimizing or dispersing vapors and

to protect personnel. Cool equipment exposed to fire with water, if it can be done safely. Avoid spreading burning

liquid with water used for cooling purposes.

Other Information

Combustion Products: Smoke, carbon monoxide, carbon dioxide, and other products of incomplete

combustion. Hydrogen sulfide and oxides of nitrogen and sulfur may be formed.

Flammable Properties: See Section 9 for Flash Point, Flammable/Explosive Limits, etc.

SECTION 6 ACCIDENTAL RELEASE MEASURES

Personal Precautions

This material may burn, but will not ignite readily. Keep all sources of ignition and hot metal surfaces away from

spill/release if safe to do so. The use of explosion-proof electrical equipment is recommended. May contain or

release poisonous hydrogen sulfide gas. If the presence of dangerous amounts of hydrogen sulfide around the


6/13


6

spilled product is suspected, additional or special actions may be warranted, including access restrictions and use

of protective equipment. Stay upwind and away from spill/release. Avoid direct contact with material. For large

spillages, notify persons down wind of the spill, isolate immediate hazard area, and keep unauthorized personnel

out. Wear appropriate protective equipment, including respiratory protection, as warranted (see Section 8).

Environmental Precautions

Stop spill/release if it can be done safely. Prevent spilled material from entering sewers, storm drains, otherunauthorized drainage systems, and natural waterways. Use foam on spills to minimize vapors. Use water

sparingly to minimize environmental contamination and reduce disposal requirements. If spill occurs on water

notify appropriate authorities and advise shipping of any hazard. Spills into or upon navigable waters, the

contiguous zone, or adjoining shorelines that cause a sheen or discoloration on the surface of the water, may

require notification of the United States National Response Center (phone number: 800.424.8802).

Containment Procedures

Carefully contain and stop the source of the spill, if safe to do so. Protect bodies of water by diking, absorbents, or

absorbent boom, if possible. Do not flush down sewer or drainage systems, unless system is designed and

permitted to handle such material. The use of fire fighting foam may be useful in certain situations to reduce

vapors. The proper use of water spray may effectively disperse product vapors or the liquid itself, preventingcontact with ignition sources or areas/equipment that require protection do not discharge solid water stream

patterns into the liquid resulting in splashing.

Clean-up Procedures

Notify relevant authorities in accordance with all applicable regulations. Immediate cleanup of any spill is

recommended. Take up with sand or other oil absorbing materials. Carefully shovel, scoop or sweep up into a

waste container for reclamation or disposal. Response and clean-up crews must be properly trained and must

utilize proper protective equipment (see Section 8).

SECTION 7 HANDLING AND STORAGE

Handling

Obtain special instructions before use. Do not handle until all safety precautions have been read and understood.

May contain or release dangerous levels of hydrogen sulfide. Avoid breathing vapors or mists. Use only outdoors

or in well-ventilated area. Wear protective gloves/clothing and eye/face protection. Wash thoroughly after

handling. Use good personal hygiene practices and wear appropriate personal protective equipment.

Storage

This material may contain or release poisonous hydrogen sulfide gas. In a tank, barge, or other closed container,

the vapor space above this material may accumulate hazardous concentrations of hydrogen sulfide. Checkatmosphere for oxygen content, hydrogen sulfide, and flammability prior to entry. Confined spaces should be

ventilated prior to entry. Keep container(s) tightly closed and properly labeled. Use and store this material in cool,

dry, well-ventilated areas away from heat, direct sunlight, hot metal surfaces, and all sources of ignition. Store

only in approved containers. The storage area should comply with NFPA 30 Flammable and Combustible Liquids

Code. Post area No Smoking or Open Flame. Keep away from any incompatible material (see Section 10).

Protect container(s) against physical damage. Outdoor or detached storage is preferred. Indoor storage should

meet OSHA standards and appropriate fire codes.

Empty containers retain residue and may be dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind,

or expose such containers to heat, flame, sparks, or other sources of ignition. They may explode and cause injury

or death. The cleaning of containers previously containing this product should follow API STD 2015 Safe Entry

and Cleaning of Petroleum Storage Tanks. All containers should be disposed of in an environmentally safe

manner and in accordance with governmental regulations. Before working on or in tanks which contain or have

contained this material, refer to OSHA regulations, ANSI Z49.1, and other references pertaining to cleaning,

repairing, welding, or other contemplated operations.

SECTION 8 EXPOSURE CONTROLS / PERSONAL PROTECTION

Suggestions provided in this section for exposure control and specific types of protective equipment are based on

readily available information. Users should consult with the specific manufacturer to confirm the performance of

their protective equipment. Specific situations may require consultation with industrial hygiene professionals.

Personal Protective Equipment

Respiratory Protection: Avoid exposure. Avoid breathing dust, fume, gas, mist, vapors, and/or spray.

Obtain special instructions before use. If engineering controls do not maintain

airborne concentrations below recommended exposure limits (where applicable)

or to an acceptable level (in countries where exposure limits have not been

established), an approved respirator must be worn. Where there is potential for

airborne exposure to hydrogen sulfide above exposure limits, a NIOSH approved,

self-contained breathing apparatus (SCBA) or equivalent operated in a pressure

demand or other positive pressure mode should be used. Under conditions

where hydrogen sulfide is not detected, a NIOSH certified air purifying respirator

equipped with organic vapor cartridges/canisters may be used. In the United

States, if respirators are used, a program should be instituted to assure

compliance with OSHA 29 CFR 1910.134. If benzene concentrations equal orexceed applicable exposure limits, OSHA requirements for personal protective

equipment, exposure monitoring, and training may apply (OSHA 29 CFR

1910.1028 Benzene).

Eye/Face Protection: The use of eye protection (such as splash goggles) that meets or exceeds ANSI

Z.87.1 is recommended when there is potential liquid contact to the eye.

Depending on conditions of use, a face shield may be necessary.

Skin Protection: The use of gloves impervious to the specific material handled is advised to

prevent skin contact. Check with manufacturers to confirm the breakthrough

performance of their products. Apron and long sleeves are recommended.

General Considerations: When using, do not eat, drink or smoke. Always observe good personal hygiene

measures, such as washing after handling the material and before eating,drinking, and/or smoking. Routinely wash work clothing and protective equipment

to remove contaminants. Handle in accordance with good safety practice.

Engineering Controls

Use process enclosures, local exhaust ventilation, or other engineering controls to control airborne levels below

recommended exposure limits. Provide adequate ventilation and minimize the risk of inhalation of vapors and

mists. If current ventilation practices are not adequate to maintain airborne concentrations below the established

exposure limits, additional engineering controls may be required.

Other Comments

This material may contain or liberate hydrogen sulfide, a poisonous gas with the smell of rotten eggs. The smell

disappears rapidly because of olfactory fatigue so odor may not be a reliable indicator of exposure. Effects ofoverexposure include irritation of the eyes, nose, throat and respiratory tract, blurred vision, photophobia

(sensitivity to light), and pulmonary edema (fluid accumulation in the lungs). Severe exposures can result in

nausea, vomiting, muscle weakness or cramps, headache, disorientation and other signs of nervous system

depression, irregular heartbeats, convulsions, respiratory failure, and death.

This material may contain varying concentrations of polycyclic aromatic hydrocarbons (PAHs), which have been

known to produce a phototoxic reaction when contaminated skin is exposed to sunlight. The effect is similar in

appearance to an exaggerated sunburn, and is temporary in duration if exposure is discontinued. Continued

exposure to sunlight can result in more serious skin problems including pigmentation (discoloration), skin

eruptions (pimples), and possible skin cancers.

This material may contain trace amounts of heavy metals, some of which may concentrate in vessels and

equipment during production and processing operations. While some of these metals are known toxins, the

hazard is dependent upon the extent of accumulation. Significant deposits of elemental mercury have the potential

to create airborne vapors of the metal, which might result in a hazardous condition. Overexposure to mercury is

known to cause neurologic effects and damage the kidneys and developing fetus.
