Elevated Work Safety Meeting

1 Elevated Work Safety Meeting 1

2 Elevated Work There are many jobs that require working at heights This requires the use of walking working surfaces such as ladders, scaffolds and stairways Safety in elevated work areas requires companies to follow strict standards for height, width, building materials, load capacity and proper housekeeping 2

3 Ladders Designed primarily to provide access to an elevated area Must not be used as a work platform unless the job can be performed using only one hand Be constructed according to OSHA regulations 3

4 Ladders Get authorization to perform elevated work Clear footing area of excess tools, debris, waste and other obstructions Place the ladder on a firm, level surface Fully open the legs of the ladder Use proper PPE Fall protection if necessary Secure tools and equipment properly Carry only necessary tools in pockets or tool belt Attach a hand line and lift items once on stable surface Maintain a 3-point contact with the ladder 4

5 3-point Contact

6 Inspect the following before using a ladder Footing Rungs or steps Side rails Hinges Spreaders Ladder Inspection 6

7 Damaged Ladders Put a warning tag on a damaged ladder immediately Report a damaged ladder to a supervisor Take a damaged ladder out of service until it is repaired Portable ladders are often damaged by being moved from worksite to worksite and while in storage Fixed ladders may deteriorate if they are exposed to the weather or corrosive chemicals 7

8 Two types of ladders commonly found in industrial facilities Portable Fixed Ladders 8

9 Portable Ladders Avoid overreaching when performing work from a ladder The worker s belt buckle must never pass the side rail of the ladder Never allow more than one person at a time on a ladder 9

10 Portable Ladders Portable ladders are subdivided into two categories Step ladders Extension ladders 10 10

11 Step Ladders A step ladder is used to perform work at relatively low levels or when an appropriate upper support is not available 11 11

12 Extension Ladders Most commonly used to transit to a higher level where permanent access is not provided Ladder footing must be on a firm, level surface to prevent the base from kicking out Open ladder must maintain a 4:1 slope Angled so the base of the ladder is one foot away from the vertical plane for each rise of four feet Top of the ladder must rest against a sturdy support Top of the ladder must extend three feet past the upper level Must be tied off to avoid slippage 12 12

13 Extension Ladders 13 13

14 Metal Ladders Never use a metal ladder when electrical hazards are present Be aware of overhead power lines and other electrical connections when setting up and moving a metal ladder 14 14

15 Fixed Ladders Provided in frequently accessed, elevated areas A visual inspection ensures it is in an acceptable condition before climbing A fixed ladder higher than 20 feet must be equipped with fall protection cages or other protective devices Rest platforms must be provided every 30 feet 15 15

16 Fixed Ladders 16 16

17 Scaffolds Designed primarily as a work platform Allow workers to perform a job that Takes a long time Requires both hands Requires more than one person Only use a scaffold for its intended purpose based on the type of scaffold used A stairway or ladder must be provided and used for climbing onto a scaffold Always place on a firm level surface 17 17

18 Scaffolds Store in a place that will avoid excessive weathering or damage Securely fasten risers and braces with the locking mechanism properly engaged Keep materials away from the bracing and footing of a scaffold Use of scaffolds that are covered with snow, ice or other slippery materials is prohibited Use of shore and lean-to scaffolds is prohibited 18 18

19 Scaffolds 19 19

20 Types of Scaffolds Pole Tube and coupler Fabricated frame Outrigger Single point adjustable suspension Two point adjustable suspension 20 20

21 Wheeled Scaffolds Can only be used on a smooth, firm, level surface Workers are only allowed on the scaffold when it is stationary 21 21

22 Qualified Worker Responsibilities Design and assembly of a scaffold Dismantle or move a scaffold Repair or alter a scaffold Determine the maximum load capacity and ensure that it is not exceeded at any time Inspection of a scaffold 22 22

23 Scaffold Inspection Must be inspected for Deterioration Damage Missing parts Must be inspected Before workers are allowed to use them Before each shift After any occurrence that may affect the stability or safe use of the scaffolding 23 23

24 Load Capacity The structure that the scaffold is secured to must be capable of withstanding the load The load includes Vertical load, such as the weight of the scaffold Horizontal load, such as the wind blowing on tarps All scaffolds and components must support, without failure, its own weight and at least four times the maximum intended load applied or transmitted to it 24 24

25 Height Limitations The height of a freestanding scaffold is limited to four times the smallest dimension of the base For example, a 5 x 10 freestanding scaffold cannot exceed a height of 20 feet tall Guying or tying is necessary if a scaffold needs to be taller Secure scaffold to a tall structure Prevent swaying or displacement Must be tied at least every 30 feet horizontally and every 26 feet vertically 25 25

26 Planking Must be made of scaffolding grade material Must completely cover the entire working platform Must form a smooth, continuous working surface Must not have any gaps large enough for tools or materials to fall through Wooden planking must extend past the end supports by no less than 6 inches and no more than 12 inches Metal planking must not extend past the end supports 26 26

27 Scaffold Hazards Electrical hazards can include Working near energized or exposed electric lines Using electric power tools Using welding equipment Scaffolds must not be closer than 10 feet to power lines Electric power tools create a risk of electrocution or shock because a metal frame scaffold is conductive Scaffold should be grounded to reduce the risk of injury To reduce the risk of electrocution or shock Use a GFCI Assured Grounding program 27 27

28 Scaffold Hazards Area above and below the work being done on a scaffold can create fall hazards Area must be inspected before the job begins and cleared of any objects with the potential to fall on workers Ladders should not be used on a scaffold to increase the working height unless specific conditions are met Workers should not stand on boxes, crates or barrels to increase their working height 28 28

29 Fall and Falling Object Protection A fall arrest system should be worn even if a scaffold is equipped with handrails The company must ensure that wearing fall protection does not create a greater hazard The tie-off point selected for a fall arrest system cannot be a part of the scaffold A hard hat must be worn at all times if there is a chance of falling hand tools, debris or other small objects 29 29

30 Fall and Falling Object Protection Eliminate the chance of materials falling from the scaffold Do not stack materials where they can be knocked off Tie hand tools and equipment to a safety line The area below the scaffold should be protected using a barricade and worker access must be restricted 30 30

31 Fall and Falling Object Protection Handrails must be installed on all open ends and sides of scaffolding greater than 10 feet high Handrails must be equipped with a top rail between 36 and 42 inches high and a mid-rail Never climb or work from the handrail, midrail, braces or cross-braces of a scaffold system Toeboards must be placed along the edge of platforms greater than 10 feet high for a distance sufficient to protect workers below Toeboards must be at least 4 inches high to prevent loose objects from being kicked over the side 31 31

32 Fall and Falling Object Protection Additional protection that will deflect or contain falling objects can include Toeboards Screens Guardrails Debris nets Catch platforms Canopy structures 32 32
