SUBJECT: Withdrawal of MSHA Approval or Certification for Certain Mine Safety 

Appliances (MSA) Products 

Who needs this information? 

Mine Safety and Health Administration (MSHA) enforcement personnel, coal and metal 

and nonmetal mine operators, miners' representatives, and repair shop facilities. 

Why is MSHA issuing this bulletin? 

This Program Information Bulletin (PIB) informs the mining industry of the withdrawal 

of MSHA approval or certification for the Mine Safety Appliances (MSA) products 

listed in Table 1 attached to this PIB. This withdrawal of approval or certification 

means that these products are no longer considered approved by MSHA. Mine 
2

operators should promptly review Table 1 and determine if any of these products are 

currently in use at their mines, and prepare to replace them with MSHA approved 

products. 

What is the effect of withdrawal of the MSHA approval? 

After December 31, 2005, the products listed in Table 1 must be removed from areas of 

mines wherever permissible equipment or an approved gas detection instrument is 

required. The products listed in Table 1 may continue to be used through 

December 31, 2005, wherever permissible equipment or approved gas detection 

instrument is required as long as the products can be maintained in approved 

condition. Replacement parts specific to the products listed in Table 1 are no longer 

available from MSA. MSA will no longer repair the products listed in Table 1. 

Mine operators that encounter difficulty in replacing the MSA products should contact 

one of the MSHA personnel listed below to request assistance. MSHA-approved 

replacement options for certain products are available from MSA as indicated in Table 

1. MSA will offer trade-in incentives for replacement of non-approved products with 

an MSHA-approved product. (We are supplying this information for the user’s 

convenience only. MSHA does not endorse or recommend any specific product.) 

MSHA-approved replacement options are also available from other manufacturers. 

What is the background for this withdrawal action? 

MSHA’s Approval and Certification Center (A&CC) has been working with MSA to 

ensure the records and documentation for all of MSA’s MSHA approved or certified 

products are accurate. 

In the process of MSA correcting the documentation for products they actively sell and 

support, MSA has requested that MSHA withdraw approvals for products that are 

obsolete and no longer in use, or for products that are in very limited use. Most of the 

products for which the approval is being withdrawn have not been produced in many 

years. 

Who can I contact at MSA? 

MSA has established the following special contact number for information regarding 

these withdrawal actions and available product replacement: 1-866-MSA-0005. 

What is the authority for this bulletin? 

30 CFR, Part 18, Part 22, Part 23
