Exosuits, also called wearable assistive devices, are mechanical or powered systems worn by workers to help support posture, reduce strain, or assist with lifting and repetitive tasks. These devices are designed to supplement human movement, not replace proper ergonomics, training, or safe work practices.

Please Note: This blog is strictly provided for informational purposes only. It is not a recommendation, endorsement, or directive for employers or employees to use exosuits as a substitute for OSHA regulations, required safety controls, or established safe work practices.

ANSI Guidance

ANSI/ASSE A10.40-2007 provides guidance for construction and industrial operations on reducing musculoskeletal injuries through safe work practices, task planning, and ergonomic controls. While the standard discusses methods to reduce strain and overexertion, it does not certify or approve exosuits as Personal Protective Equipment (PPE). Instead, ANSI emphasizes that any assistive technology must be evaluated for task suitability, hazards, and worker safety before use.

OSHA’s Position

It is important to understand that OSHA does not approve, certify, or endorse exosuits. OSHA also does not currently recognize exosuits as PPE. Employers remain fully responsible for complying with OSHA requirements related to ergonomics, hazard control, and injury prevention. Exosuits may be used as a supplemental tool, but they do not replace OSHA-required controls, such as proper lifting techniques, engineering controls, job rotation, or rest breaks.

Potential Benefits

When properly evaluated and used, exosuits may offer limited benefits for certain tasks. Possible benefits include the following:

• Reduced muscle fatigue during repetitive or awkward tasks
• Additional support for bending, lifting, or overhead work
• And, increased worker awareness of posture and movement

Limitations and Risks

Exosuits are not a solution for unsafe work conditions and can introduce new hazards if misused. Important limitations include the following:

• They may create a false sense of security and encourage overexertion
• Poor fit or improper use can increase strain or restrict movement
• They do not eliminate pinch points, struck-by hazards, or fall risks
• And, extended use may cause discomfort or secondary injuries

Safe Use Considerations

ANSI A10.40-2007 emphasizes hazard reduction through planning and controls. When exosuits are used, the following considerations should be applied:

• Conduct a job hazard analysis before introducing exosuits
• Use exosuits only for tasks they are specifically designed to assist
• Provide training on proper fit, use, and limitations
• Monitor workers for signs of fatigue, discomfort, or restricted movement
• And, reevaluate tasks regularly to ensure risks are actually reduced

Worker Responsibilities

Workers play a key role in safe exosuit use. Employees should always do the following:

• Use exocuits only if authorized and trained
• Report discomfort, pain, or equipment issues immediately
• Never modify or bypass exosuit components
• And, continue to follow all lifting, ergonomic, and safety procedures

Critical Reminder!

Exosuits are not approved, certified, or recognized by OSHA as personal protective equipment. While ANSI may reference exosuits in guidance documents, ANSI has no regulatory or enforcement authority, and its standards are voluntary unless adopted by an employer.

Workers must verify with their employer whether exosuits are permitted on the job. Even when allowed, exosuits are supplemental tools only and must never replace OSHA-required safe work practices, ergonomic controls, proper lifting techniques, training, or hazard mitigation.

Bottom line: Exosuits may be covered in ANSI guidance, but they are not a substitute for OSHA compliance or proven ergonomic controls.
