Findings From the National Machine Guarding Program-A Small Business Intervention: Machine Safety.

OBJECTIVES: The purpose of this nationwide intervention was to improve machine safety in small metal fabrication businesses (3 to 150 employees). The failure to implement machine safety programs related to guarding and lockout/tagout (LOTO) are frequent causes of Occupational Safety and Health Administration (OSHA) citations and may result in serious traumatic injury. METHODS: Insurance safety consultants conducted a standardized evaluation of machine guarding, safety programs, and LOTO. Businesses received a baseline evaluation, two intervention visits, and a 12-month follow-up evaluation. RESULTS: The intervention was completed by 160 businesses. Adding a safety committee was associated with a 10% point increase in business-level machine scores (P < 0.0001) and a 33% point increase in LOTO program scores (P < 0.0001). CONCLUSIONS: Insurance safety consultants proved effective at disseminating a machine safety and LOTO intervention via management-employee safety committees.

Findings From the National Machine Guarding Program: A Small Business Intervention: Lockout/Tagout.

OBJECTIVE: Failure to implement lockout/tagout (LOTO) procedures adversely affects the rate of work-related fatalities and serious traumatic injury and is one of the most frequently cited Occupational Safety and Health Administration standards. This study assesses the impact of a nationwide intervention to improve LOTO in small metal fabrication businesses. METHODS: Insurance safety consultants conducted a standardized and validated evaluation of LOTO programs and procedures. Businesses received a baseline evaluation, two intervention visits, and a 12-month follow-up evaluation. RESULTS: The intervention was completed by 160 businesses. The mean LOTO procedure score improved from 8% to 33% (P < 0.0001), the mean program score went from 55% to 76% (P < 0.0001), and the presence of lockable disconnects went from 88% to 92% (P < 0.0001). CONCLUSIONS: This nationwide intervention showed substantial improvements in LOTO. It provides a framework for assessing and improving LOTO.

National Machine Guarding Program: Part 1. Machine safeguarding practices in small metal fabrication businesses.

BACKGROUND: Metal fabrication workers experience high rates of traumatic occupational injuries. Machine operators in particular face high risks, often stemming from the absence or improper use of machine safeguarding or the failure to implement lockout procedures. METHODS: The National Machine Guarding Program (NMGP) was a translational research initiative implemented in conjunction with two workers' compensation insures. Insurance safety consultants trained in machine guarding used standardized checklists to conduct a baseline inspection of machine-related hazards in 221 business. RESULTS: Safeguards at the point of operation were missing or inadequate on 33% of machines. Safeguards for other mechanical hazards were missing on 28% of machines. Older machines were both widely used and less likely than newer machines to be properly guarded. Lockout/tagout procedures were posted at only 9% of machine workstations. CONCLUSIONS: The NMGP demonstrates a need for improvement in many aspects of machine safety and lockout in small metal fabrication businesses.

National Machine Guarding Program: Part 2. Safety management in small metal fabrication enterprises.

BACKGROUND: Small manufacturing businesses often lack important safety programs. Many reasons have been set forth on why this has remained a persistent problem. METHODS: The National Machine Guarding Program (NMGP) was a nationwide intervention conducted in partnership with two workers' compensation insurers. Insurance safety consultants collected baseline data in 221 business using a 33-question safety management audit. Audits were completed during an interview with the business owner or manager. RESULTS: Most measures of safety management improved with an increasing number of employees. This trend was particularly strong for lockout/tagout. However, size was only significant for businesses without a safety committee. Establishments with a safety committee scored higher (55% vs. 36%) on the safety management audit compared with those lacking a committee (P < 0.0001). CONCLUSIONS: Critical safety management programs were frequently absent. A safety committee appears to be a more important factor than business size in accounting for differences in outcome measures.
