Repeal Section 4226:

4226. Definitions.

NOTE: Authority cited: Section 142.3, Labor Code. 

Amend Section 4227 as follows:

4227. Squaring Metal Shears.

(a) Mechanical power and foot and hand power squaring metal shears shall be provided with a guard which will prevent the hands of the operator from entering the zone traveled by the knives of the shears while they are in motion. This guard may be a fixed barrier, set not more than 3/8-inch above the table (or in accordance with Figure G-8 and Table G-3 of Section 4186), or a self-adjusting barrier with a limit of 3/8-inch above the table, but that will automatically rise to the thickness of the material.

(b) Automatic clamps of "hold-downs" on squaring metal shears, when cut-outs are filled in with plastic or screen, will be acceptable as a guard. Hydraulic or pneumatic hold-downs shall be guarded by U shaped guards coming down to provide a clearance of not more than 3/8-inch between the table and the bottom of the guard or by other means or methods which will provide equivalent protection for the employee.

(c) When squaring metal shears are guarded by means of a strip of heavy metal in front of the knife, the strip shall be set at such an angle with the table that the cutting line will be visible to the operator.
