According to OSHA (Occupational Safety and Health Administration), falls, tripping, slipping, and falling down stairs account for 15-20% of all workplace accidents related to working at height in factories.

Although specific statistical data for Vietnam is not as widely published as in the United States, applying global procedures and international standards, we can conclude that falls while using stairs are a significant accident risk in factories.

Therefore, OSHA has standardized and disseminated the 3-point of contact rule in its safety guidelines for using industrial ladders and stairs.

I. What is the Three Point of Contact Rule?

This rule emphasizes that when climbing up or down stairs (or mobile ladders, factory climbing ladders), workers must maintain at least three points of contact with the steps:

• Two hands and one foot
• Two feet and one hand.

This helps workers maintain better balance, distribute weight evenly, and reduce the likelihood of losing control and falling.

II. Where did the three-point of contact rule originate?

No one invented the 3-Point of Contact Rule. It has been developed and standardized by international occupational safety organizations based on practical research into fall accidents.

1. OSHA (USA)
OSHA has officially incorporated the 3-Point Contact Rule into its safety guidelines for using industrial ladders and stairs. The rule applies to:

• Ladder safety
• Fall Prevention
• Industrial Access Safety

OSHA considers the 3-Point of Contact Rule a core principle for preventing slips and falls.

2. ANSI – American National Standards Institute

ANSI incorporates the 3-point of contact rule into technical standards such as:

• Ladder design
• User manuals
• Safety operating procedures (SOPs)

3. NIOSH – National Institute for Occupational Safety and Health

NIOSH is the leading scientific research body on:

• Analysis of balance forces
• Hand-foot movements
• Causes of imbalance when climbing ladders

NIOSH concludes that maintaining at least 3 contact points significantly reduces the risk of imbalance.

4. Other international safety associations

This rule was subsequently adopted by:

• ISO (International Organization for Standardization)
• HSE (UK)
• European and Asian safety associations in global safety training.

Therefore, the 3-point of contact rule is considered a “global best practice,” becoming a default safety standard in modern manufacturing.

III. Why is this rule important for ladder safety?

1. Increased stability and balance

By maintaining three points of contact with the ladder, our bodies have better support, reducing the risk of slipping or losing balance.

2. Better movement control

With three fixed points of contact, each step we take on the ladder is more tightly controlled, especially important when carrying heavy objects or tools.

3. Reduced risk of accidents when working at height

Losing balance while climbing stairs is a common cause of injuries, trauma, or even serious accidents in factory work environments. Therefore, the three-point rule is one of the effective measures to prevent accidents when climbing stairs.

IV. The Role of AI Technology in Monitoring the 3-Point of Contact Rule

Although factory safety regulations are very strict and workers are always trained and tested on safety knowledge while working in the factory, they can sometimes forget and unintentionally violate the rules, especially during long shifts or in areas with many stairwells.

This is where Safety AI CCTV plays its role: automatically identifying violations of the 3-Point rule, providing immediate warnings, and helping businesses shift from passive training to proactive prevention.

• Real-time violation identification
• Instant warnings via lights, sirens, and SMS notifications to the safety department
• Visual data display on the dashboard allows safety monitors to track violation trends by shift/area and time.
• Event data is recorded so the SHE team can continuously train and improve.

With this solution, the factory can not only monitor hazardous behavior but also prevent accidents before they happen, instead of just reviewing incidents with conventional surveillance cameras.

V. Enhancing Comprehensive Factory Safety

The 3-point of contact rule is one of the fundamental principles of workplace safety. However, for continuous enforcement in a production environment with many people and multiple shifts, a surveillance camera system like Safety AI CCTV helps businesses:

• Ensure compliance with safety rules
• Monitor in real time from anywhere
• Integrate alert and reporting data to improve EHS processes
• Build a sustainable safety culture

VI. Let Safety AI CCTV Ensure Factory Safety for You

Following these three rules when using stairs is essential to factory safety culture. This simple step can minimize the risk of slips, falls, and dangerous accidents. When combined with a camera technology system like Safety AI CCTV, businesses can enhance monitoring, warning, and risk prevention more safely.
