Polymercaptan 407

Guidance on Safe Use

First-aid measures

Emergency measure - Inhalation: Move the exposed person to fresh air. If not breathing, give

artificial respiration. If breathing is difficult, give

oxygen. Get medical attention if symptoms continue.

Emergency measure - Eyes: Flush eyes with water immediately while holding the eyelids

open. Remove contact lenses, if worn, after initial flushing

and continue flushing for at least 15 minutes.  Get

medical attention if irritation persists.

Emergency measure - Skin: To remove the material from skin, use soap and water.

Discard contaminated clothing and shoes or thoroughly clean

before re-use. Get medical attention if any symptoms develop

.

Emergency measure - Ingestion: If swallowed, do not induce vomiting. Give the person a

glass of water or milk to drink and get immediate medical

attention. Never give anything by mouth to an unconscious

person.

Fire-fighting measures

Recommended extinguishing agent: Extinguishing media: Use water fog, foam, dry chemical or

carbon dioxide (CO2) to extinguish flames.

Protection of fire fighters:

Fire fighting instructions: This material will burn although

it is not easily ignited. For fires involving this

material, do not enter any enclosed or confined space

without proper protective equipment, including self-

contained breathing apparatus.

Product arising from burning: Combustion products: Highly dependent on combustion

conditions.  A complex mixture of airborne solids, liquids

and gases including carbon monoxide, carbon dioxide and

unidentified organic compounds will be evolved when this

material undergoes combustion.

Product determined by test: N

Protective equipment: For fires involving this material, do not enter any enclosed

or confined space without proper protective equipment,

including self-contained breathing apparatus.

Accidental release measures

Emergency measures in case of spillage: Protective measures: eliminate all sources of ignition in

the vicinity of the spill or released vapor.  If the

material is released into the work area, evacuate the area

immediately. Monitor area with combustible gas indicator.

Spill management: stop the source of the release if you can

do it without risk. Contain to prevent further contamination

of soil, surface water or ground water. Clean up spill as

soon as possible, observing precautions in Exposure

Controls/Personal Protection. Use appropriate techniques

such as applying non-combustible sorbent materials or

pumping. Where feasible and appropriate, remove contaminated

soil. Place contaminated materials in disposable containers

and dispose of in a manner consistent with applicable

regulations. Spill residues and contaminated soil may be

deodorized using dilute (5%) aqueous solutions of bleach

(sodium hypochlorite). Alternatively, household bleach in a

pure solution may be used. Do not use concentrated or dry

bleach. Absorb in dry, inert material. Do not attempt to

neutralize or deodorize bulk liquid mercaptan. Concentrated

bleach will cause heating and possible ignition. Attempts to

neutralize bulk liquid mercaptan with bleach solutions will

be ineffective and only serve to increase the amount of

liquid to dispose.

Handling and storage

Handling: Precautionary Measures: Avoid breathing vapor or fumes which

may be released through thermal processing.

Static Hazard: Electrostatic charge may accumulate and

create a hazardous condition when handling this material. To

minimize this hazard, bonding and grounding may be

necessary but may not, by themselves, be sufficient. Review

all operations, which have the potential of generating an

accumulation of electrostatic charge and/or a flammable

atmosphere, and use appropriate mitigating procedures.

Engineering controls: If heated material generates vapor or

fumes, use process enclosures, local exhaust ventilation, or

other engineering controls to control exposure. Use in a

well-ventilated area.

Eye/Face Protection: Wear suitable eye protection such as

safety glasses, chemical goggles, or face-shields if

engineering controls or work practices are not adequate to

prevent eye contact.

Skin Protection: Wear impervious clothing to prevent skin

contact.  Selection of protective clothing may include

gloves, apron, boots and complete facial protection

depending on operations conducted. Users should determine

acceptable performance characteristics of protective

clothing. Suggested materials for protective gloves include

:Neoprene or Nitrile Rubber.

Respiratory Protection: No respiratory protection is

normally required. If heating material generates vapor or

fumes that are not adequately controlled by ventilation,

wear a NIOSH approved respirator. Use the following elements

for air-purifying respirators: Air Purifying Respirator for

Organic Vapors, Dusts and Mists. Use a positive pressure,

air-supplying respirator if there is potential for

uncontrolled release, exposure levels are not known, or

other circumstances where air-purifying respirators may not

provide adequate protection.

Storage: The material will be stored in a heated tank under nitrogen

atmosphere.

Packaging of the substance and or preparation: Initial production is into railcars for transport to the EU,

then possibly off load into lorries.

Disposal considerations

Industry - Possibility of recovery/recycling: Stop the source of the release if you can do it without

risk. Contain to prevent further contamination of soil,

surface water or ground water. Clean up spill as soon as

possible, observing precautions in Exposure

Controls/Personal Protection. Use appropriate techniques

such as applying non-combustible sorbent materials or

pumping. Where feasible and appropriate, remove contaminated

soil. Place contaminated materials in disposable containers

and dispose of in a manner consistent with applicable

regulations.

Industry - Possibility of neutralisation: Spill residues and contaminated soil may be deodorized using

dilute (5%) aqueous solutions of bleach (sodium

hypochlorite). Alternatively, household bleach in a pure

solution may be used. Do not use concentrated or dry bleach.

Absorb in dry, inert material. Do not attempt to

neutralizeor deodorize bulk liquid mercaptan. Concentrated

bleach will cause heating and possible ignition. Attempts to

neutralize bulk liquid mercaptan with bleach      solutions

will be ineffective and only serve to increase the amount

of liquid to dispose

Industry - Possibility of destruction: controlled discharge: Any liquid waste from spills or contaminated raw material

will be shipped to a registered waste disposal facility.

Industry - Possibility of destruction - water purification: No liquid waste is anticipated from storage and transfer

activities.
