Confined Space Safety Products

Confined spaces present unique and often dangerous hazards to workers. These spaces, such as tanks, vessels, silos, storage bins, hoppers, vaults, and pits, are characterized by limited entry and exit points, poor natural ventilation, and the potential for hazardous atmospheres. At Tend Supplies, we understand the critical importance of confined space safety. We offer a comprehensive range of confined space safety equipment and resources designed to protect workers from the risks associated with entering and working in these challenging environments, ensuring compliance with OSHA regulations and industry best practices.

1. Understanding the Hazards of Confined Spaces

Confined spaces can pose a variety of hazards, including:

  • Hazardous Atmospheres: Oxygen deficiency, flammable gases or vapors, toxic gases (e.g., carbon monoxide, hydrogen sulfide).
  • Engulfment: Risk of being engulfed by materials such as grain, sand, or liquids.
  • Entrapment: Confined spaces may have inwardly converging walls or a floor that slopes and tapers to a smaller cross-section.
  • Physical Hazards: Moving machinery, exposed electrical components, falling objects.

 Essential Confined Space Safety Equipment

Working safely in confined spaces requires specialized equipment and rigorous procedures. Tend Supplies offers a wide range of products to address these needs:

1 Gas Monitors:

  • Description: Gas monitors are essential for detecting hazardous atmospheres in confined spaces. They measure the levels of oxygen, flammable gases, and toxic gases, providing real-time readings and alerts.
  • Types:
    • Single-Gas Monitors: Detect a specific gas (e.g., carbon monoxide).
    • Multi-Gas Monitors: Detect multiple gases simultaneously (e.g., oxygen, lower explosive limit (LEL), carbon monoxide, hydrogen sulfide).
  • Key Features to Consider:
    • Sensor Types: Electrochemical, catalytic bead, photoionization detectors (PIDs).
    • Alarm Levels: Audible, visual, and vibrating alarms.
    • Data Logging: Ability to record and download gas readings.
    • Durability: Rugged construction to withstand harsh environments.
  • Recommendations:
    • Honeywell BW GasAlert Series: Reliable and widely used multi-gas monitors.
    • MSA Altair Series: Known for their durability and ease of use.
    • RAE Systems MultiRAE: Offers advanced features and sensor options.

2 Ventilation Equipment:

  • Description: Proper ventilation is crucial for removing hazardous gases and providing fresh air to workers in confined spaces.
  • Types:
    • Blowers: Supply fresh air into the confined space.
    • Exhaust Fans: Remove contaminated air from the confined space.
  • Key Features to Consider:
    • Airflow Capacity (CFM): Choose a blower or fan with sufficient airflow for the size of the confined space.
    • Explosion-Proof: Essential when working in potentially flammable atmospheres.
    • Ducting: Flexible ducting to direct airflow to and from the confined space.
  • Recommendations:
    • Allegro Ventilation Blowers: Known for their durability and performance.
    • Euramco Safety Blowers: Offer a range of explosion-proof options.

3 Retrieval Systems:

  • Description: Retrieval systems are used to rescue workers from confined spaces in case of an emergency.
  • Components:
    • Tripod or Davit System: Provides a stable anchor point above the confined space opening.
    • Winch or Hoist: Used to raise and lower the worker.
    • Self-Retracting Lifeline (SRL): Provides fall protection during entry and exit.
  • Key Features to Consider:
    • Load Capacity: Must be able to support the weight of the worker and any equipment.
    • Ease of Use: The system should be easy to set up and operate.
    • Durability: Built to withstand harsh environments and emergency situations.
  • Recommendations:
    • 3M DBI-SALA Confined Space Retrieval Systems: Industry-leading systems known for their reliability.
    • Miller by Honeywell Confined Space Entry/Retrieval Kits: Offer comprehensive solutions for various applications.

4 Harnesses and Lanyards:

  • Description: Full-body harnesses and lanyards are essential for fall protection when entering and exiting confined spaces, and may be used as part of a retrieval system.
  • Key Features:
    • D-Ring Placement: Appropriate D-ring locations for fall arrest and retrieval.
    • Adjustability: Ensure a proper fit for the worker.
    • Durability: Built to withstand the forces of a fall.
  • Recommendations:
    • 3M Protecta Harnesses
    • Guardian Fall Protection Harnesses and Lanyards

Confined Space Entry Procedures:

In addition to having the right equipment, it's crucial to follow established confined space entry procedures:

  • Permit-Required Confined Space (PRCS) Program: Develop and implement a comprehensive PRCS program as required by OSHA.
  • Atmospheric Testing: Test the atmosphere before entry and continuously monitor it during work.
  • Ventilation: Provide adequate ventilation to maintain a safe atmosphere.
  • Training: Ensure all workers involved in confined space entry are properly trained.
  • Rescue Plan: Develop a detailed rescue plan and have trained personnel and equipment readily available.
  • Attendant: A designated attendant must remain outside the confined space to monitor the workers inside and initiate rescue if needed.

Frequently Asked Questions (FAQs)

Q1: What is a confined space?

A1: OSHA defines a confined space as a space that: 1) Is large enough for an employee to enter and perform work; 2) Has limited or restricted means for entry or exit; and 3) Is not designed for continuous employee occupancy.  

Q2: What is a permit-required confined space (PRCS)?

A2: A PRCS is a confined space that has one or more of the following characteristics: 1) Contains or has a potential to contain a hazardous atmosphere; 2) Contains a material that has the potential for engulfing an entrant; 3) Has an internal configuration such that an entrant could be trapped or asphyxiated; or 4) Contains any other recognized serious safety or health hazard.  

Q3: What are the most common atmospheric hazards in confined spaces?

A3: Oxygen deficiency, flammable gases or vapors, and toxic gases like carbon monoxide and hydrogen sulfide are common atmospheric hazards.

Q4: How often should gas monitors be calibrated?

A4: Gas monitors should be calibrated according to the manufacturer's recommendations, typically every 3-6 months, or more frequently in harsh environments. Bump testing should be performed before each use.

Q5: Where can I find OSHA regulations for confined space entry?

A5: OSHA's standard for confined space entry is 29 CFR 1910.146. You can find this standard on the OSHA website.
