Pre-Start Health and Safety Reviews

When Do You Need a Machine Guarding Assessment?

A machine guarding assessment is often needed when there is uncertainty about whether equipment is properly safeguarded or compliant with applicable requirements. 

It requires a thorough understanding of how workers interact with the equipment and where practical controls are needed to reduce risk.

Clients often contact HITE Engineering when:

  • New machinery is being installed
  • Existing equipment has been modified
  • Guards have been removed, damaged, bypassed, or are outdated
  • Operators may be exposed to pinch, crush, shear, nip, cutting, rotating, or entanglement hazards
  • An internal safety audit has identified guarding gaps
  • A Ministry of Labour or inspector concern has been raised
  • There is uncertainty about whether a PSR/PHSR applies
  • Lockout, hazardous energy, or safeguarding concerns need review
  • Legacy equipment needs to be assessed against current expectations

Machine Guarding Compliances

Our Machine Guarding Assessment Process

HITE’s machine guarding engineers follow a clear assessment process so clients know what to expect.
01
Step 1

Intake and Equipment Details

We begin by reviewing the information available, such as equipment photos, manuals, drawings, layout information, modification details, known safety concerns, inspection notes, or project timelines.

02

Step 2

Site Visit or Documentation Review

Depending on the scope, our team may complete an on-site assessment or begin with a review of documentation.
A site visit is often needed when machine interaction, access points, guarding condition, or operating conditions must be reviewed directly.
03
Step 3

Hazard and Safeguarding Review

HITE reviews how workers interact with the equipment during operation, setup, cleaning, maintenance, troubleshooting, and other routine tasks.
Our team evaluates existing guards, protective devices, emergency stops, access points, safe distance considerations, and the interaction between safeguarding and lockout requirements.
04
Step 4

Recommendations and Reporting

HITE provides recommendations based on the assessment findings.
Depending on the project, this may include a deficiency summary, engineering guidance, design direction, documentation, or a formal report.
05
Step 5

Design or Remediation Support

Where additional support is needed, HITE can assist with guarding design direction, retrofit recommendations, or further engineering documentation.

FAQs

Machine guarding is a safety shield or cover that is placed on or around an engineering or manufacturing machine to prevent hazardous areas of a machine from coming in contact with the body parts of its operators or employees.
  • Point of operation: This is the starting point where operators perform their work on the machine, such as cutting, melting, shaping, or forming materials or stock. 
  • The power transmission device: This part of a machine or equipment contains the mechanical system which transfers the power to the area of the machine that performs the work. These pieces include cranks, pulleys, belts, gears, connecting rods, chains, and spindles. 
  • The operating controls: Each machine comes with a mechanical or electrical power control that makes it possible for the operator to turn on or stop the power from continuing. For this reason, the operating controls need machine guarding to protect the operator from injury.

Common examples include:

  • Fixed guards: These safeguards consist of gates, fences, or blade covers and contain no moving parts. They are used to prevent machine operators from encountering hazardous situations at the operation points. 
  • Interlocking guards: These types of safeguards are made with movable parts that can cut off the power supply or shut down when tampered with. 
  • Adjustable guards: These guards are attached to engineering machines permanently. However, their moving parts can be manually adjusted to accommodate various operating conditions.
  • Self-adjusting guards: These kinds of safeguards automatically adjust to the machine operator when they start interacting with the dangerous part of the machine. For instance, the self-adjusting guards shut down when the machine is idle.

A machine guarding assessment may be needed when equipment is new, modified, damaged, missing guards, or flagged during a safety audit or compliance review.

It may also be needed when operators are exposed to pinch, crush, shear, nip, rotating, cutting, or entanglement hazards.

Yes. New equipment should still be reviewed before use.

Employers and end users are responsible for workplace safety and compliance. Manufacturer-supplied equipment may not address every site-specific requirement, process condition, or Ontario workplace obligation.

Yes, certain new equipment, modifications, or safeguarding changes may require a PSR/PHSR.

HITE can help determine whether a PSR/PHSR applies and, where required, support the engineering review and documentation process.

Well-designed safeguarding should protect workers without creating unnecessary barriers to safe, normal use.

HITE considers operator interaction, maintenance access, workflow, and production needs when providing guarding or safeguarding recommendations.

Effective safeguards should help prevent contact with hazardous moving parts, be durable, remain securely in place, and avoid creating new hazards.

They should also allow necessary work to be completed safely and reduce the chance of objects or body parts entering hazardous areas.
