Ladders and Platforms

Fixed Ladders

This inspection helps to ensure that fixed ladders around the rig are of the proper size and configuration required to provide safe access for employees. For more information see: 29 CFR 1910.27 and OSHA Stairways and Ladders Guide (publication 3124).

Keep track of all current fixed ladders on the rig to facilitate thorough and accurate inspections and maintenance. Fixed ladders both outside on the rig and inside of tanks and substructures should be listed for inspection and maintenance.

Location/Use

Write the location of each fixed ladder and its use. This description can be used for identification. Examples of use include: limited access for maintenance or for more regular use during the course of the day.

Anchor Points

Inspect the connection for any cracked welds or bent brackets. Anchor points are places where the fixed ladder attaches to the main structure and can be welded, bolted or a combination of both.

Check that bolts are tight and the connection does not move at the attachment point. Check that the top and bottom of the ladder are attached to prevent movement when getting on and off the ladder.

Fixed Ladders (Continued)

Side Rails and Rungs

Check that the rungs of the ladder are straight, evenly spaced, and firmly attached to the side rails. Check that rungs are a minimum of ¾ inches in diameter for metal ladders and welded solid to the side rails. Any loose or missing rungs should be replaced immediately. Make sure that rungs and side rails are free of burrs and snags that may grab a user’s glove.

Landings

Check that all access points to fixed ladders are open and clear of debris. Any signs regarding access to the ladder should be posted at these points. Check that fixed ladder side rails extend at least 3.5 feet above the top level of access. If the top access of the ladder presents a fall hazard, make sure the opening is gated or chained off to prevent falls through the opening.

Fall Protection

For ladders that exceeds 20 feet in unbroken length, make sure some type of fall protection is available. This can be a ladder cage, retractable life line ("SRL"), or cable follower system.

Portable Ladders

portable ladders

Make sure you don’t forget this inspection to ensure that portable ladders around the rig are in good condition and the proper size for safe access for employees. For more information see: 29CFR1910.25- 26 and OSHA Stairways and Ladders Guide (publication 3124).

Keep track of all current portable ladders on the rig to facilitate thorough and accurate inspections and maintenance.

Location/Use

Write the location and general use of each portable ladder on the rig. Portable ladders should be stored close to the point of use if possible. The use may be for limited access or for more regular use during the course of the day. Check that ladders are stored by hanging them up or placing them in a designated rack where they will not be damaged by other rig activities. Damaged ladders must be removed from service and replaced.

Portable Ladders (Continued)

Feet and Levelers

Check the area of the ladder where it sets down on the supporting surface. Check the feet for any missing or bent traction devices. Check that rivets are tight and the connection does not move at the attachment point unless it is designed to do so.

Examine factory attachments to be sure they are in place and functioning properly. Bent or “sprung” ladders should be taken out of service.

Visible Rating

Ladders must be marked with ladder size, type, maximum length, number of sections (if appropriate), highest standing level, total length of sections (if applicable), model number, manufacturer’s name, manufacturer’s location, and date of manufacture. Usage guidelines and other warning statements must also be placed on the ladders in specific locations depending on ladder type. Ladders appropriate for electrical work should be available and clearly identified. Check that ladders are available which are appropriate for the rig workers at that site.

Fixed Platforms

support structure

Do this inspection to ensure that platforms around the rig are of the proper size and configuration required to provide safe working surfaces for employees. For more information see: 29CFR1910.23.

Location/Use

List each fixed platform for easy identification along with the original designed purpose of the platform.

Support Structure

Check that frame work is straight and spaced to provide adequate support for grating or decking. Check that knee braces or angle braces are straight, undamaged, and do not have any cuts or welds that would weaken the original design. Check that there are not any additional equipment or tools hanging from the support structure beyond what it was designed to hold.

Hinges & Attachments

Check for weld cracks or deformities that could fail when the platform is in use. Ensure that properly sized pins and keepers are installed and secure.

On fold-down platforms, check for pinch points and heavy lifting exposure when rigging up or down.

Fixed Platforms (Continued)

guardrails

Working Surface

Check that the working surface of the platform is even and free from dents or level changes that would create trip hazards. Check that the surface is not worn to the point that it fails to provide reasonable slip protection for normal work activities. Make sure the walking or working area is not cluttered with tools or equipment.

Guard Rails

Check that rails have a solid top rail, mid rail, and 4” kick plate on the bottom to prevent tools from being knocked off the platform.

Removable rails that have the potential to be snagged and pulled out of their sockets when lifting loads should be drilled and safety bolted into the pin pockets.

Video

Improving health and safety performance in the Canadian Oil and Gas industry will come about through timely changes in culture. Safety Stand Down provides an opportunity for leaders to get out of their offices and into the field to visit with front line workers to demonstrate commitment and recieve feedback on safe operations.
