	responsibility of the laboratory facility to establish internal policies and
	procedures relative to processing instruments that have or may have been
	exposed to CJD. If instruments exposed to CJD are processed in
	accordance with the World Health Organization (WHO) Infection Control
	Guidelines for Transmissible Spongiform Encephalopathies (TSE), there
	are:
	POTENTIAL HAZARDS TO OPERTORS AND REPAIR PERSONNEL:
	• Be sure to wear personal protective equipment (PPE) when handling
	NaOH liquids.
	• Heated NaOH liquids have the potential to injure personnel who handle
	the containers.
	• Heated NaOH liquids can emit fumes that can be corrosive to eye tissue
	and can cause respiratory distress.
	• Cleaning residual NaOH from the chamber interior could lead to skin
	burns and the production of NaOH aerosol mist.
	POTENTIAL DAMAGE TO THE STERILIZER:
	• Processing caustic chemicals inside sterilizers is not recommended.
	• NaOH is corrosive to copper and brass and has the potential to damage
	the chamber and lower piping.
p. 4-5, 4-12, 4-14, 5-2, 5-6	BURN HAZARD: The door and chamber area could be HOT enough to
	cause burns. Wear personal protective equipment (PPE) when loading the
	chamber.

400LS/500LS Series Steam Sterilizers

WARNING

“Warning” notes alert the user to the possibility of personal injury.

p. 3-14	POSSIBILITY OF INJURY: Observe the following loading
	recommendations:
	• The rack can support a maximum load of 100 lbs. An individual shelf can
	hold up to 100 lbs., evenly distributed.
	• Do not place more than 20 lbs. on the end of an extended shelf.
	• Liquid loads (hot or cold) should never be placed on an extended shelf.
	Do not extend a shelf with liquid loads (hot or cold).
p. 3-1	HOT SURFACES: The chamber and the gasket area could be HOT. Turn
	OFF the controls and make sure the sterilizer is cool before cleaning the
	gasket or removing the sediment screen for cleaning.
p. 4-12, 4-14, 5-15	BURN HAZARD: Before removing the load, manually lower the door
	approximately one inch to allow residual steam to escape. Stand back to
	avoid possible burns when lowering the door
p. 4-12	HOT SURFACES: The loading car or rack and shelves may be hot enough
	to cause burns. Wear protective gloves and eyewear when removing the
	load from the chamber.
p. 4-5, 4-12, 4-15	POSSIBILITY OF INJURY: Do not operate the door while loading or
	unloading the sterilizer.
p. 4-12	RISK OF CONTAMINATION: After removing wrapped goods from the
	chamber, inspect for residual moisture (wet packs). Moisture on or within a
	package can potentially create a pathway for migration of microorganisms
	from the outside to the inside of a sterilized package.
p. 3-2, 4-11, 5-10, 5-16, 6-3, 6-17	POSSIBILITY OF INJURY: If a WATER IN DRAIN message displays, DO
	NOT open the chamber door manually. Hot water in the chamber may spill
	out if the door is opened. Wait until the message clears before attempting to
	open the door.

p.3-2, 3-7, 4-5, 4-7, 4-10, 4-13, POSSIBILITY OF INJURY: Only use vented or open containers to process 4-15, 5-2, 5-6, 5-9, 5-13, 5-16 liquids in this sterilizer. Use of sealed, unvented containers to process

	liquids can result in severe personal injury due to container breakage.
