equipment. Product should be worked up in closed equipment as far as possible. Keep away from food, drink
and animal feeding stuffs.
Protection against fire and explosion:
Prevent electrostatic charge - sources of ignition should be kept well clear - fire extinguishers should be kept
handy. The product is capable of dust explosion. Avoid dust formation.
General advice:
Keep container tightly closed and dry.
8. Exposure Controls and Personal Protection

Advice on system design:
Provide local exhaust ventilation to control dust.

Personal protective equipment
Respiratory protection:
Wear a NIOSH-certified (or equivalent) particulate respirator. Observe OSHA regulations for respirator use (29
CFR 1910.134).
Hand protection:
Wear chemical resistant protective gloves., Consult with glove manufacturer for testing data.
Eye protection:
Tightly fitting safety goggles (splash goggles) (e.g. EN 166)
Body protection:
Body protection must be chosen depending on activity and possible exposure, e.g. head protection, apron,
protective boots, chemical-protection suit.
General safety and hygiene measures:
Do not breathe dust. Avoid contact with the skin, eyes and clothing. Under no circumstances should the product
come into contact with the skin of pregnant women or be inhaled by them. Females of childbearing age should
not come into contact with the product. Remove contaminated clothing immediately and dispose of safely. Keep
separated from food stuffs and feed stocks. When using, do not eat, drink or smoke. At the end of the shift the
skin should be cleaned and skin-care agents applied. Employees should shower at the end of the shift.

NFPA Hazard codes:
Health : 2 Fire: 1 Reactivity: 0 Special:
HMIS III rating

Safety Data Sheet
Oxybutynin Hydrochloride
Revision date : 2011/09/28
NFPA and HMIS use a numbering scale ranging from 0 to 4 to indicate the degree of hazard. A value of zero means that the substance possesses essentially no hazard; a rating of four indicates extreme danger. Although similar, the two rating systems are intended for different purposes, and use different criteria. The NFPA system was developed to provide an on-the-spot alert to the hazards of a material, and their severity, to emergency responders. The HMIS system was designed to communicate workplace hazard information to employees who handle hazardous chemicals. We support worldwide Responsible Care® initiatives. We value the health and safety of our employees, customers, suppliers and neighbors, and the protection of the environment. Our commitment to Responsible Care is integral to conducting our business and operating our facilities in a safe and environmentally responsible fashion, supporting our customers and suppliers in ensuring the safe and environmentally sound handling of our products, and minimizing the impact of our operations on society and the environment during production, storage, transport, use and disposal of our products.
