Safety Advisory MSA Topgard® Protective Cap


Safety Advisory

Topgard®  Protective Cap


June 20, 2017


Dear Valued Head Protection Customer,


MSA recently determined that white Topgard Protective Caps manufactured in January and February 2017 may not comply with the electrical insulation performance requirement as defined in the ANSI/ISEA Z89.1-2014 American National Standard for Industrial Head Protection. The affected Topgard helmets with white shells were shipped from MSA between January 31, 2017 and March 8, 2017. MSA is voluntarily replacing these helmets free of charge.


Additional testing on helmets from this time period indicated that the helmet shell may crack during the ANSI/ISEA specified top

impact test. Although complying with the ANSI force transmission requirement, affected helmets that crack will exceed the allowable electrical leakage during the ANSI/ISEA specified electrical resistance test.


Identifying Affected Helmets:

To identify affected helmets, check that the helmet shell is white and a cap style, with a brim only in the front. Also check that the label inside the helmet shell confirms that it is a “Topgard” model, as shown below. Then, check the shell mold date emblem on the underside of the helmet brim, as indicated in the photo below. If the shell was molded in January 2017 or February 2017, the helmet is affected and should be removed from service and replaced. All other helmet models, colors, and shell mold dates are not affected.
