* As a rule of thumb, start with a shade that is too dark to see the weld zone. Then go  
to a lighter shade that gives a sufficient view of the weld zone without going below the  
minimum. In oxyfuel gas welding or cutting where the torch produces a high yellow  
light, it is desirable to use a filter lens that absorbs the yellow or sodium line in the  
visible light of the (spectrum) operation.  
** These values apply where the actual arc is clearly seen. Experience has shown  
that light filters may be used when the arc is hidden by the workpiece.

(b) When insulating equipment is tested pursuant to these rules, the equipment  
current may not exceed 1 microampere per kilovolt of phase-to-phase applied voltage.  
Note 1 to subrule (3): This rule shall apply to equipment that provides primary  
insulation of employees from energized parts. It does not apply to equipment used for  
secondary insulation or equipment used for brush contact only.  
Note 2 to subrule (3): For alternating current excitation, this current consists of the  
following three components:  
(a) Capacitive current because of the dielectric properties of the insulating material  
itself.  
(b) Conduction current through the volume of the insulating equipment.  
(c) Leakage current along the surface of the tool or equipment.  
The conduction current shall be normally negligible. For clean, dry insulating  
equipment, the leakage current shall be small, and the capacitive current shall  
predominate.  
Note 3 to subrule (3): Plastic guard equipment is considered to conform to the  
performance requirements of this rule, if it meets, and is used in accordance with ASTM  
F-712 “Standard Test Methods and Specifications for Electrically Insulating Plastic  
Guard Equipment for Protection of Workers,” 2006 edition with 2011 supplement, as  
adopted in R 408.13301a.  
History: 2015 AACS.  
R 408.13389 In-service care and use of electrical protective equipment.  
Rule 3389. (1) Electrical protective equipment shall be maintained in a safe, reliable  
condition.  
(2) The following specific requirements apply to rubber insulating blankets, rubber  
insulating covers, rubber insulating line hose, rubber insulating gloves, and rubber  
insulating sleeves.  
(3) Maximum use voltages shall conform to those listed in Table D.  
(4) An employer shall ensure that insulating equipment is inspected for damage  
before each day’s use and immediately following any incident that can reasonably be  
suspected of causing damage. Insulating gloves shall be given an air test, along with the  
inspection.  
Note to subrule (4): ASTM F-1236 “Standard Guide for Visual Inspection of  
Electrical Protective Rubber Products,” 1996 Edition with 2012 supplement, as adopted  
Page 33  
Courtesy of www.michigan.gov/orr  
in R 408.13301a, presents methods and techniques for the visual inspection of electrical  
protective equipment made of rubber. This guide also contains descriptions and  
photographs of irregularities that can be found in this equipment.  
(5) Insulating equipment with any of the following defects shall not be used.  
(a) A hole, tear, puncture, or cut.  
(b) Ozone cutting or ozone checking, that is, a series of interlacing cracks produced  
by ozone on rubber under mechanical stress.  
(c) An embedded foreign object.  
(d) Any of the following texture changes:  
(i) Swelling.  
(ii) Softening.  
(iii) Hardening.  
(iv) Becoming sticky or inelastic.  
(v) Any other defect that damages the insulating properties.  
(6) An employer shall ensure that insulating equipment found to have other defects  
that might affect its insulating properties is removed from service and returned for testing  
under subrules (10) and (11) of this rule.  
(7) An employer shall ensure that insulating equipment is cleaned as needed to  
remove foreign substances.  
(8) Insulating equipment shall be stored in a location and in a manner as to protect it  
from all of the following:  
(a) Light.  
(b) Temperature extremes.  
(c) Excessive humidity.  
(d) Ozone.  
(e) Other damaging substances and conditions.  
(9) Protector gloves shall be worn over insulating gloves, except under the following  
conditions:  
(a) Protector gloves need not be used with class 0 gloves, under limited-use  
conditions, when small equipment and parts manipulation necessitate unusually high  
finger dexterity.  
Note to subrule (9)(a): Persons inspecting rubber insulating gloves used under these  
conditions shall take extra care in visually examining them. Employees using rubber  
insulating gloves under these conditions shall take extra care to avoid handling sharp  
objects.  
(b) If the voltage does not exceed 250 volts, ac, or 375 volts, direct current, protector  
gloves shall not be used with class 00 gloves, under limited-use conditions, when small  
equipment and parts manipulation necessitate unusually high finger dexterity.  
Note to subrule (9)(b): Persons inspecting rubber insulating gloves used under these  
conditions shall take extra care in visually examining them. Employees using rubber  
insulating gloves under these conditions shall take extra care to avoid handling sharp  
objects.  
(c) Any other class of glove may be used without protector gloves, under limited-use  
conditions, when small equipment and parts manipulation necessitate unusually high  
finger dexterity but only if the employer can demonstrate that the possibility of physical  
Page 34

damage to the gloves is small and if the class of glove is 1 class higher than that required  
for the voltage involved.  
(d) Insulating gloves that have been used without protector gloves may not be reused  
until they have been tested under the provisions of this rule.  
(10) Electrical protective equipment shall be subjected to periodic electrical tests.  
Test voltages and the maximum intervals between tests shall be pursuant to Table D and  
Table E.  
(11) The test method used in this rule shall reliably indicate whether the insulating  
equipment can withstand the voltages involved.  
Note to subrule (11): The standard electrical test methods considered as meeting this  
requirement are listed in Table 3.  
(12) Insulating equipment failing to pass inspections or electrical tests shall not be  
used by employees, except as follows:  
(a) Rubber insulating line hose may be used in shorter lengths with the defective  
portion cut off.  
(b) Rubber insulating blankets may be salvaged by severing the defective area from  
the undamaged portion of the blanket. The resulting undamaged area shall not be smaller  
than 560 millimeters by 560 millimeters (22 inches by 22 inches) for class 1, 2, 3, and 4  
blankets.  
(c) Rubber insulating blankets shall be repaired using a compatible patch that results  
in physical and electrical properties equal to those of the blanket.  
(d) Rubber insulating gloves and sleeves with minor physical defects, such as small  
cuts, tears, or punctures, shall be repaired by the application of a compatible patch. Also,  
rubber insulating gloves and sleeves with minor surface blemishes shall be repaired with  
a compatible liquid compound. The repaired area shall have electrical and physical  
properties equal to those of the surrounding material. Repairs to gloves shall be permitted  
only in the area between the wrist and the reinforced edge of the opening.  
(13) An employer shall ensure that repaired insulating equipment is retested before it  
is used by employees.  
(14) The employer shall certify that equipment has been tested pursuant to the  
requirements of this rule. The certification shall identify the equipment that passed the  
test and the date it was tested and shall be made available upon request to the department  
of licensing and regulatory affairs director and to MIOSHA employees or their authorized  
representatives.  
Note to subrule (14): Marking equipment with, and entering onto logs, the results of  
the tests and the dates of testing are acceptable means of meeting the certification  
requirement.
