Why Zero Motion Detection Matters for Machine Safety

Zero motion detection technology is essential for safeguarding workers from hidden dangers that remain even after machinery powers down. By ensuring that equipment has fully stopped before access is granted, these systems help prevent injuries, improve compliance, and strengthen overall safety programs.

Key Advantages Include:

Prevents Premature Access: Stops gates, guards, or doors from unlocking until machine components have completely stopped rotating.
Reduces Serious Injuries: Protects operators from residual kinetic energy hazards that occur in the final stages of machine movement.
Enhances Compliance: Supports compliance with OSHA 1910.212 machine guarding requirements and ANSI B11.19 performance criteria for safeguarding.
Improves Safety Protocols: Works seamlessly with interlocks, controls, and automation systems to create layered safety protection.
Reduces Liability: Minimizes costly downtime, accidents, and potential legal risk by ensuring safe, documented access control.

Our Turnkey Electrical Guarding Process

From concept to compliance, we can handle every step:

On-Site Assessment

Our TÜV-certified safety engineers at Arrow & Machine Safety Specialists conduct comprehensive risk assessments, reviewing your equipment against OSHA 1910.212, ANSI B11, ISO 13849, and ISO 14120 standards. We identify hazards and define the safeguarding strategy tailored to your operation.

Custom Design

Using advanced CAD and 3D modeling, we engineer guarding systems that integrate seamlessly with your equipment. Every design balances operator access, visibility, ventilation, and maintenance requirements while meeting regulatory standards.

Fabrication

Arrow fabricates components in-house using premium materials such as steel, aluminum, and polycarbonate. We deliver precision framing, gasketing, hardware, and electrical safeguarding devices built to perform in demanding industrial environments.

Installation

Our expert installation team integrates your system with interlocks, safety switches, sensors, and control devices for full reliability. We ensure that your guarding solution functions as intended without compromising productivity.

Testing & Validation

Post-installation, we verify safety performance and provide relevant compliance documentation. Our team also supports training, audits, and certification requirements, helping your facility stay inspection-ready and OSHA-compliant.

Common Applications & Industries

Our Zero Motion Detection Systems are ideal in any application with moving or spinning equipment:

Manufacturing Lines: Presses, shears, lathes, and other rotary systems.
Automotive Assembly: Ensure safe re-entry to conveyor or robotic zones.
Machining & CNC Operations: Detect spindle stop before door opens.
Packaging Equipment: Detect residual belt or roller motion before reloading.
Pharmaceutical & Chemical: Stop agitators or mixers before lid access.

Designed to Meet or Exceed Safety Standards

Our guarding systems are built to align with:

  • OSHA 29 CFR 1910 Subpart O – Machinery and Machine Guarding
  • ANSI B11.19 – Performance Criteria for Safeguarding
  • ISO 14120 – General Requirements for Guard Design

Proactive compliance helps you reduce risk, avoid OSHA citations, and improve operator safety. Whether you’re safeguarding one machine or modernizing an entire production line, we can help. Expect fast quotes, clear timelines, and expert guidance from start to finish.

Is zero motion detection required by OSHA?

OSHA does not mandate zero motion detection by name, but it requires employers to prevent employee exposure to machine hazards under 29 CFR 1910.212. Zero motion detection is a recognized safeguarding method used to meet OSHA’s general machine guarding requirements when residual motion presents a risk.

How does zero motion detection improve compliance audits?

Zero motion detection provides documented, verifiable control over access to hazardous motion. This helps demonstrate due diligence during OSHA inspections, internal audits, and third-party safety assessments by showing that access is restricted until equipment is confirmed safe.

Is zero motion detection the same as lockout/tagout?

No. Zero motion detection is not a replacement for lockout/tagout (LOTO). It is a complementary safeguarding measure used during normal operation, setup, or maintenance tasks where full LOTO is not required but residual motion still poses a hazard.

Who should design and install zero motion detection systems?

Zero motion detection systems should be designed and installed by qualified machine safety professionals. TÜV-certified safety engineers ensure the system meets OSHA requirements, aligns with ANSI and ISO standards, and is properly validated for the specific application.
