SAFETY DATA SHEET SUPERSEDES:REVISION: AprilJune 2,5, 20182023
NYACOL® AL20SD and AL20DW-SD VERSION NO.: 3
Avoid inhalation, ingestion and contact with eyes. General occupational hygiene measures are required to ensure a
safe handling of the substance. These measures involve good personal and housekeeping practices (i.e. regular
cleaning with suitable cleaning devices), no eating, drinking and smoking at the workplace and wearing standard
working clothes and shoes unless otherwise stated. Wash hands after use. Remove contaminated clothing and
protective equipment before entering eating areas. Shower and change clothes at end of work shift. Do not wear
contaminated clothing at home.
7.2 Conditions for safe storage, including any incompatibilities
Periods of exposure to high temperatures should be minimized. Water contamination should be avoided. Provide
sufficient ventilation in storage and workrooms. Store in a cool dry area. Keep containers tightly sealed.

USA OSHA OSHA PEL Ceiling 5 mg/M3 TWA
8.2 Exposure Controls
Engineering Controls: Ventilation adequate to meet occupational exposure limits.
Hygiene Measures: Workers should wash exposed skin several times daily with soap
and water. Soiled work clothing should be laundered or dry-
cleaned.
Respiratory: Airborne concentrations should be kept to lowest levels
possible. If vapor, mist or dust is generated and the
occupational exposure limit of the product, or any component
of the product, is exceeded, use appropriate NIOSH or MSHA
approved air purifying or air supplied respirator after
determining the airborne concentration of the contaminant. Air-
supplied respirators should always be worn when airborne
concentrations of the contaminant or oxygen content is
unknown.
Hands: Wear impervious gloves such as neoprene.
Eyes: Safety glasses, chemical type goggles, or face shield
recommended to prevent eye contact.
Skin: Wear clean body-covering clothing; impervious gloves such as
neoprene. Workers should wash exposed skin several times
daily with soap and water. Soiled work clothing should be
laundered or dry-cleaned.
Environmental Exposure Controls: Adverse effects of this material on the environment have not
been evaluated. Proper disposal techniques to isolate and
recover material should be implemented.
