Appropriate Engineering
Controls:
Ventilation must be adequate to maintain the ambient workplace atmosphere
below the exposure limit(s) outlined in the safety data sheet.
Individual Protection Measures:
Eye/ Face Protection
Use approved safety goggles or safety glasses. If necessary, refer to
appropriate regulations and standards.
Skin and Body
Protection:
Skin: Wear chemical impervious gloves (eg: Nitrile or Neoprene). Use triple
gloves for spill response. If necessary, refer to appropriate regulations and
standards.
Body: Use protection appropriate for task (eg: lab coat, coveralls, Tyvek suit).
If necessary, refer to OSHA Technical Manual (Sec. VII: Personal Protection
Equipment) or appropriate Standards of Canada. Use foot protection, such as
described in appropriate regulations and standards.
Respiratory Protection:
If mists or sprays are created, use appropriate respiratory protection. Oxygen
levels below 19.5% considered IDLH by OSHA. In such instances, use full-
facepiece pressure demand SCBA or a full facepiece, supplied air respirator
with auxillary self-contained air supply.
General Hygiene
considerations:
Handle in accordance with good industrial hygiene and safety practices.
