2.8 Airless Spray Guns
2.8.1 Guarding
Airless spray guns of the type that atomize paints and fluids at high pressures (1,000 pounds or more per
square inch) must be equipped with automatic or visible manual safety devices that will prevent pulling of
the trigger to prevent release of the paint or fluid until the safety device is manually released.
In lieu of the above, a diffuser nut that will prevent high pressure, high velocity release, while the nozzle tip
is removed, plus a nozzle tip guard that will prevent the tip from coming into contact with the operator, or
other equivalent protection, must be provided.

2.9 Jacks
All
jacks
must be designed so that their maximum safe extension cannot be exceeded.
To raise the rated load of a jack, the point of application of the load, the applied force, and the length of
lever arm should be those designated by the manufacturer for the particular jack considered.
2.9.1 Use
In the absence of a firm foundation, the base of the jack must be blocked. If there is a possibility of slippage
of the cap, a block must be placed in between the cap and the load.
Workers are not permitted to enter the zone beneath a jack-supported load unless it has been effectively
blocked or cribbed.
2.9.2 Marking
The rated load of a jack must be legibly and permanently marked on a prominent location on the jack by
casting, stamping, or other suitable means.
2.9.3 Cleaning and Maintenance
Hydraulic jacks exposed to freezing temperatures must be supplied with an adequate antifreeze liquid.
All jacks requiring periodic cleaning and lubrication, such as screw jacks, must be properly cleaned and
lubricated at regular intervals.
2.10 Portable Winches
Portable winches
Must be secured against accidental shifting while in use
Must be fitted with limit switches if workers have access to areas from which it is possible to be drawn
into the winch
2.11 Microtomes
2.11.1 Use
Microtomes
(manual, automatic, and semi-automatic) must be used, operated, and maintained by qualified

Tissue sections or sections of any other material sliced by the microtome must be retrieved by the worker
using forceps and/or other appropriate tool(s).
2.11.2 Guarding
When not in use, the foot treadle of each electrically powered microtome must be guarded by a cover or
guard that will prevent unintended operation.
2.11.3 Cleaning and Maintenance
The adjustment, removal, replacement, or maintenance activities of microtomes must comply with the
requirements of
Chapter 51, “Control of Hazardous Energy”
.
At a minimum, microtome operators must be trained in the requirements of
8 CCR 3558
.
