First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

Remove person to fresh air and keep comfortable for breathing. Supply fresh air or oxygen; call for doctor. In case of unconsciousness place patient stably in side position for transportation.

Skin contact

Immediately wash with water and soap and rinse thoroughly. Seek immediate medical advice.

Eye contact

Rinse opened eye for several minutes under running water. Then consult a doctor. Call a doctor immediately.

Ingestion

Rinse mouth. Do not induce vomiting; call for medical help immediately.

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

CO2, powder or water spray. Fight larger fires with water spray or alcohol resistant foam.

Specific hazards

Formation of toxic gases is possible during heating or in case of fire. In case of fire, the product promotes combustion. May decompose explosively in absence of fire due to formation of vapour-air-mixture.

Instructions

Remove undamaged containers from the danger zone. Cool endangered receptacles with water spray.

Firefighter Protection

Wear self-contained respiratory protective device. Do not inhale explosion gases or combustion gases.

06

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Emergency procedures

Keep unprotected persons away. Ensure adequate ventilation. Use suitable respiratory protective device in case of insufficient ventilation. Avoid contact with the eyes and skin. Keep away from ignition sources.

Environmental

Do not allow to enter sewers/ surface or ground water. Inform respective authorities in case of seepage into water course or sewage system.

Cleanup methods

Collect with an inert, non-combustible, absorbent material

Materials: inert, non-combustible, absorbent material (i.e. sand, diatomaceous earth, acid binder, universal binder)

07

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Keep receptacles tightly sealed. Open and handle receptacle with care. Do not return unused material to original containers – decomposition hazard! Restrict the quantity stored at the work place. Resistant to inert materials only. Avoid naked flames, sparks, other ignition sources and sunlight. Avoid any direct contact with accelerators. Weigh out and mix separately when processing polyester resins. Avoid storage in containers with an airtight closure to prevent hazardous pressure build-up due to an eventual decomposition. Avoid contact with the eyes and skin. Ensure good ventilation/exhaustion at the workplace. Do not inhale gases / fumes / aerosols. Adhere to the workplace limit values and / or other threshold values.

Storage

Store in a cool location. Store only in the original receptacle. Store in cool, dry conditions in well sealed receptacles. Protect from heat and direct sunlight. Protect from contamination. Store receptacle in a well ventilated area. Store under lock and key and out of the reach of children. Recommended storage temperature: 10 - <30 °C.

Hygiene

Avoid contact with the eyes and skin. Do not inhale gases / fumes / aerosols. Adhere to the workplace limit values and / or other threshold values.

Fire prevention

Protect from heat. Protect from sunlight. Prevent impact and friction. Avoid naked flames, sparks, other ignition sources and sunlight. Protect against electrostatic charges. Keep apart from incompatible substances, dirt and high temperatures.

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Engineering

Ensure good ventilation/exhaustion at the workplace.

Hands

Protective gloves. The glove material has to be impermeable and resistant to the product/ the substance/ the preparation. Selection of the glove material on consideration of the penetration times, rates of diffusion and the degradation. Neoprene gloves, PVC gloves, Synthetic rubber gloves. The exact break trough time has to be found out by the manufacturer of the protective gloves and has to be observed.

Eyes

Tightly sealed goggles

Respiratory

Use suitable respiratory protective device in case of insufficient ventilation. In case of brief exposure or low pollution use respiratory filter device. In case of intensive or longer exposure use self-contained respiratory protective device. Filter A/P2

Skin/Body

Protective work clothing

Stability and Reactivity

Chemical stability, hazardous reactions, and incompatible materials

Stability

No decomposition if used and stored according to specifications. Resistant to inert materials only. Suitable materials: Stainless steel (DIN 1.4571), PVC, polyethylene, glass-lined apparatus.

Reactivity

No decomposition if used according to specifications.

Hazardous reactions

Thermal decomposition or direct contact with numerous additives, such as reducing agents (i.e. amine accelerator), heavy metal compounds (in particular cobalt accelerators), acids and alkaline solutions, may lead to hazardous, autoaccelerating decomposition reactions, and possibly, to explosion or fire.

Avoid

Protect from heat. Avoid naked flames, sparks, other ignition sources and sunlight. To avoid thermal decomposition do not overheat. Thermal decomposition with temperatures above 60 °C (SADT)

Incompatible

Keep apart from dirt, rust, chemicals, especially reducing substances, acids, alkaline solutions, amines and heavy metal compounds (such as accelerator, dessicative, metal soaps) Avoid any direct contact with accelerators.

Decomposition

Formation of various organic degradation products and inflammable and explosive vapours/gases upon decomposition. Danger of forming toxic pyrolysis products.
