Purpose
The purpose of this SOP is to establish uniform procedures for the safe handling, securement, and storage of compressed gas cylinders to prevent leaks, physical damage, and injuries associated with sudden gas release or cylinder tip-over.
Scope
This procedure applies to all personnel involved in receiving, moving, using, or storing compressed gas cylinders at any Ryxen-affiliated or client industrial facility. It covers cylinders containing oxygen, acetylene, propane, nitrogen, and other compressed gases, excluding cryogenic liquids.
Safety Precautions
- Before connecting or disconnecting any gas cylinder, ensure the system is depressurized and the valve is closed. Use lockout/tagout procedures if the cylinder is part of a manifold system.
- Wear safety glasses with side shields or a full-face shield, impact-resistant gloves, and steel-toed boots during cylinder handling. For certain gases (e.g., acetylene) use flame-resistant clothing.
- Never use a cylinder as a roller, wedge, or support. Keep cylinders upright at all times and secure with chains or straps.
- Store cylinders in a well-ventilated area, separated by gas type (flammable vs. oxidizer) by at least 20 ft or a 1-hour fire-rated wall. Full and empty cylinders must be stored separately with ‘FULL’ and ‘EMPTY’ tags.
Required Tools & Materials
- Compressed gas cylinder(s) with appropriate valve protection cap
- Cylinder cart or hand truck with chain/strap
- Chain, strap, or floor bracket for securement
- Safety tags (FULL/EMPTY) and markers
- Proper regulator for the gas type
- Leak detection solution (soap-and-water spray)
- Personal protective equipment (PPE) as listed above
- Fire extinguisher (rated for gas fires) nearby
Procedure: Step-by-Step
1
Inspect all incoming cylinders for visible damage: dents, bulges, burns, corrosion, or compromised valve caps. Reject any damaged cylinders and notify supplier.
2
Ensure the valve protection cap (if supplied) is securely in place before moving the cylinder. Never lift a cylinder by the cap.
3
Transport cylinders using an approved cylinder cart or hand truck. Secure the cylinder(s) to the cart with a chain or strap. Do not roll or slide cylinders horizontally.
4
At the point of use, place the cylinder in an upright position on a level, non-combustible surface. Secure the cylinder to a wall bracket, bench, or cart to prevent tip-over.
5
Before attaching a regulator, briefly crack the cylinder valve to clear dust/debris. Stand to the side of the valve opening, not in front.
6
Attach the regulator hand-tight, then open the cylinder valve slowly. Use a soap-and-water spray to check for leaks at all connections. If bubbles appear, close valve, tighten connections, and retest.
7
When not in use, close the cylinder valve completely, bleed the regulator, and relieve all pressure. Replace the valve protection cap if the cylinder is disconnected.
8
Return empty cylinders to the designated storage area, clearly tagged ‘EMPTY’, and secure them. Store full and empty cylinders separately.
