 Lakeland Tychem SL Level B
Tychem® SL is the lightweight fabric that provides effective and economical protection against a broad range of chemicals. It's a laminate of Tyvek® spun bonded olefin by DuPont and Saranex® 23-P film from Dow Chemical. Lakeland designs Tychem® SL protective garments with sealed seams and storm-flapped zippers. Available in white, Tychem® SL is the only Saranex laminated material for which DuPont supplies permeation data and technical support.
Level B situations call for the highest degree of respiratory protection but a lesser need for skin protection. It calls for SCBA or positive pressure supplied air respirator with escape SCBA, plus hooded chemical resistant clothing (overalls and long sleeved jacket; coveralls; one or two piece chemical-splash suit; or disposable chemical-resistant coveralls.
