ALDRICH - 405736 www.sigma-aldrich.com Page 2
(EU). Where risk assessment shows air-purifying respirators are
appropriate use a full-face respirator with multi-purpose
combination (US) or type ABEK (EN 14387) respirator cartridges as
a backup to engineering controls. If the respirator is the sole
means of protection, use a full-face supplied air respirator.
Hand: Compatible chemical-resistant gloves.
Eye: Chemical safety goggles.
GENERAL HYGIENE MEASURES
Wash contaminated clothing before reuse. Wash thoroughly after
handling.
