R 408.10033 Machine controls .  
Rule 33. (1) Powered electrical equipment shall have an on-off switch .  
(2) When unexpected motion would cause injury, an actuating machine control,  
except for an emergency device for a powered fixed or transportable machine,

(3) Unless its function is self-evident, each operating control device shall be  
identified as to its function .  
(4) A powered machine that is attended by more than 1 employee shall be equipped  
with an actuation device for each employee who is exposed to a point of operation  
hazard. The machine shall activate only after concurrent use of all actuation devices .

hazard exists that could cause an injury or the actuation of the controls shall require  
continuous depression during the hazardous portion of the machine cycle .  
(7) Equipment that is operated in series so that one piece of equipment  
automatically supplies another shall be interlocked so that when any equipment in the

History: 1979 AC; 1993 AACS.  
R 408.10034 Machine guards and devices.  
Rule 34. (1) Two hand-control devices shall be the anti-tie down type and located in  
a manner to prevent bridging. Operation shall require manual activation of both controls  
until a point is reached in the cycle where the operator cannot remove his or her hands  
and place them within a pinch point. If repeating would cause an injury, an anti-repeat  
device shall be incorporated into the control system.  
(2) Guards shall be secured to the machine, if possible, or to other fixed objects. The  
guard shall not create a hazard in itself.  
(3) A point of operation guard or device shall be as prescribed in a specific standard,  
or, in the absence of a specific standard, shall be designed and constructed, when  
required, to prevent the machine operator exposed to the hazard from having any part of  
his or her body in the hazardous area during the operating cycle. A guard or device for  
the point of operation of a nonproduction arbor press or straightening press is not  
required if the machine is equipped with a hand control that is designed to stop the ram  
action or return the ram to the up position when released .  
(4) Hand tools shall not be substituted for the required guarding or point of operation  
devices, except that a hand tool may be used as prescribed in subrule (5) of this rule for a  
press brake operation. Where hand tools are used for placing into, and removing material  
from, a point of operation, they shall be designed so that the operator is not required to  
place a hand within the point of operation.  
(5) A bending operation on a press brake involving less than 25 pieces of 1 specific  
bend, if not guarded, shall require the use of a hand tool when the operator must hold the  
work piece within 4 inches of the point of operation, and a conspicuous sign shall be  
posted on the machine stating "Hand tools shall be used to hold stock."  
(6) A revolving barrel, container, or drum exposed to contact shall be guarded by a  
standard barrier, an enclosure, or equivalent protection where a hazard exists. Access  
through a standard barrier or enclosure shall be by a gate equipped with an interlock,  
which shall disconnect the power when the gate is opened and require manual  
re-actuation of a start button. A constant pressure jog control that bypasses the interlock  
may be used to aid loading and unloading.  
Page 5  
(7) Blades of a fan, located within 7 feet of a floor or working level and used for  
ventilation or cooling of an employee, shall be guarded with a firmly affixed or secured  
guard. Any opening in the guard shall have not more than 1 of its dimensions more than 1  
inch and the distance to the blade shall not be less than that prescribed in Table 1.  
(8) A fan used in process cooling whose blade is less than 7 feet above the floor or  
working level shall meet the distance requirements of Table 2. Where the openings are  
larger than those shown in Table 2, the distance from the guard to the blade shall prevent  
any part of the employee's body from making contact with the blade.  
(9) When an employee is exposed to a hazard created by a pinch point other than  
point of operation, the hazard shall be guarded or the employee otherwise protected.  
(10) A band or circular saw shall be guarded as prescribed in General Industry  
Safety and Health Standard Part 27 “Woodworking Machinery,” as referenced in  
R 408.10002.  
(11) An extractor, parts washer, or tumbler, manually controlled and equipped with  
an inside revolving cylinder, shall be equipped with a cover or door interlocked in such a  
manner as to prevent opening the door when the inside cylinder is in motion, and to  
prevent power operation of the inside cylinder when the cover or door is open. An inch  
control or constant pressure control which bypasses the interlock may be used to aid  
loading and unloading.  
(12) An employee shall not place his or her body beneath equipment, such as  
vehicles, machines, or materials, supported only by a jack, overhead hoist, chain fall, or  
any other temporary single supporting means, unless safety stands, blocks or other  
support system capable of supporting the total imposed weight is used to protect the  
employee in case of failure of the supporting system.

air hose shall be less than 30 pounds per square inch gauge when dead-ended.

a fixed or removable shield, safely located, shall be provided to protect an employee in an  
adjacent area.
