WALKING-WORKING SURFACES 29 CFR 1910 SUBPART D Bureau of Workers’ Comp PA Training for Health & Safety (PATHS) This presentation is designed to assist trainers conducting OSHA 10-hour General Industry outreach training for workers. Since workers are the target audience, this presentation emphasizes hazard identification, avoidance, and control – not standards. No attempt has been made to treat the topic exhaustively. It is essential that trainers tailor their presentations to the needs and understanding of their audience. This presentation is not a substitute for any of the provisions of the Occupational Safety and Health Act of 1970 or for any standards issued by the U.S. Department of Labor. Mention of trade names, commercial products, or organizations does not imply endorsement by the U.S. Department of Labor. PPT-036-02

Introduction Slips, trips and falls cause: The majority of general industry accidents 15 percent of all accidental deaths More fatalities than all other causes, except motor vehicles OSHA’s standards for walking and working surfaces apply to all permanent places of employment, except where only domestic, mining or agricultural work is performed. 29 CFR Part 1910 Subpart D Walking-Working Surfaces (§1910.21 to 1910.30) PPT-036-02

General Requirements: Housekeeping Workplaces must be kept clean, orderly and sanitary. Workroom floors must be maintained as clean and dry as possible. Some of the most frequently cited violations in Subpart D involve housekeeping [1910.22(a)]. Drainage must be maintained and gratings, mats or raised platforms must be provided where wet processes are used. Every floor, working place and passageway must be kept free from protruding nails, splinters, holes, or loose boards to facilitate cleaning. PPT-036-02

Open-sided Floors and Platforms Open-sided floors or platforms 4’ or more above adjacent floor or ground level must be guarded by a standard railing (or equivalent) on all open sides, except where there is an entrance to a ramp, stairway or fixed ladder. A toeboard is required when beneath the open sides: persons can pass, there is moving machinery, or there is equipment where falling materials could create a hazard. 1910.23(c)(1) Unguarded Platform PPT-036-02

Open-sided Floors, Walkways, Platforms and Runways Regardless of height, a standard railing and toeboard must be used to guard: open-sided floors - walkways - platforms, or - runways Above or adjacent to dangerous equipment, pickling or galvanizing tanks, degreasing units and similar hazards 1910.23(c)(3) PPT-036-02

Does not apply to stairs used for fire exit purposes, to construction operations, to private residences, or to articulated stairs, such as those on floating roof tanks. Fixed industrial stairs are required for access to and from places of work where operations necessitate regular travel between levels. Violation here: several steps bent and damaged, no railings/handrails, tools on stairs PPT-036-02

Portable Ladders Ladders used to gain access to a roof or other area must extend at least 3’ above the point of support. Remove defective ladders from service and tag or mark “Dangerous, Do Not Use” Never use ladders in a horizontal position as scaffolds or work platforms. Never use metal ladders near electrical equipment. 1910.25 1910.26 Maximum length: Stepladders – 20 ft, single-rung ladders – 30 ft., two-section rung ladders – 60 ft. Stepladders must be equipped with a metal spreader or locking device to securely hold the front and back sections in an open position. All ladders must be inspected periodically, kept in good condition at all times, and must be free from sharp edges, splinters, oil grease, or other defects which would affect their use. - Always place the ladder on secure footing and lock in place. - Short ladders shall not be spliced together to make long ladders. - The top of a regular stepladder shall not be used as a step. - Always face the ladder when climbing or descending. Notice step ladder in use; safer to use straight ladder PPT-036-02

Portable Wood Ladders Free from sharp edges, splinters, wear and decay Step ladders - Type I = 3’ to 20’ (heavy duty use) - Type II = 3’ to 12’ (medium duty) - Type III = 3’ to 6’ (light duty) These have a metal spreader or locking device PPT-036-02

Portable Wood ladders - Inspection 29 CFR 1910.25 (d)(1)(x) Regularly inspect ladders Those with defects should be withdrawn from service for repair or destruction and tagged or marked as "Dangerous, Do Not Use" PPT-036-02

Single/Straight ladder Portable Ladders Single/Straight ladder 30 feet or less Extension ladder 60 feet or less Painter’s ladder 12 feet or less The length of a stepladder is measured by the length of the front rail. To be classified as a standard length ladder, the measured length must be within plus or minus one-half inch of the specified length. Stepladders must not exceed 20 feet. The bottom four rails are to be supplied with an insulating non-slip material for the safety of the user. Metal ladders conduct electricity. PPT-036-02 *

Care and Use of Ladders Ladders must be maintained in good condition at all times: Joints must be tight Metal bearings of lock, wheels, pulleys, etc., must be lubricated Frayed or badly worn rope must be replaced Safety feet and other auxiliary equipment must be in good condition Ladders must be inspected frequently PPT-036-02

Ladders and Electricity Metal ladders conduct electricity – be careful where they are located when in use Suggest metal ladders have a sign stating “not for use around electricity or electrical lines” PPT-036-02

Ladder Angle – Portable Rung and Cleat Ladders Use at angle where the horizontal distance from the top support to the foot of the ladder is ¼ the working length of the ladder (length along ladder between the foot and top support) 1910.25 PPT-036-02

Safe Use of Ladders Make sure the ladder is strong enough and long enough for the job. Carefully inspect the ladder before you use it. Place the ladder on a firm, level surface with its feet parallel to the wall it is resting against. Face the ladder when ascending or descending. PPT-036-02

Safe Use of Ladders Ensure rungs are free from grease/oil. Always maintain 3 points of contact when ascending or descending. Never splice ladders together. Employee is maintaining three points of contact while working PPT-036-02

Fixed Ladders Permanently attached to a structure, building or equipment Cages or wells are required if longer than 20’ to a maximum unbroken length of 30’ Ladder safety devices may be used on tower, water tank and chimney ladders over 20’ in unbroken length instead of cage protection 1910.27 All fixed ladders must be inspected regularly and be maintained in a safe condition. Preferred pitch in range of 75 to 90 degrees with horizontal. PPT-036-02

Safe Use of Ladders – Any Safety Issues Here? Rail Bent Rail Bent Bracket Bent & Shelf Missing Bracket Bent & Shelf Missing PPT-036-02

Scaffolding General Requirements Must be capable of supporting four times the maximum intended load. Do not alter or move while in use. Protect workers on scaffolds from overhead hazards. If higher than 10’, use guardrails, midrails and toeboards. Use wire mesh between the toeboard and guardrail if people work or pass underneath. Must be equipped with access ladder or equivalent. 1910.28 Damaged or weakened scaffolds must not be used. A safe means must be provided to gain access to the working platform level through use of a ladder, ramp, etc. Never work on scaffolds during storms, high winds, ice, or snow. Always be aware of the hazards of overhead power lines when working on scaffolds. PPT-036-02

Scaffolding Designed by qualified person and built loaded to design Footing or anchorage of scaffolds must be sound, rigid and capable of carrying the maximum intended load without displacement Must be capable of supporting at least 4 times the maximum intended load PPT-036-02

Any Problems Here? Scaffolding unsafe – no guardrails, not supported or anchored properly, etc. PPT-036-02

Summary • Slips, trips and falls constitute the majority of general industry accidents. • OSHA’s standards for walking and working surfaces include requirements for guarding floor/wall openings and holes, housekeeping, industrial stairs and ladders. • Maintaining proper clearance and aisle space helps to prevent accidents and injuries. • Keeping working surfaces clean, dry and uncluttered can prevent many workplace accidents. PPT-036-02

Remember A slip/trip/fall can occur in just one second, and that one second can change your life. Be careful, be safe and use common sense when it comes to maintaining and using walking and working surfaces. PPT-036-02
