81 SAFE WORK REQUIREMENTS PERTAINING TO STAIRS AND FIXED LADDERS

82 STAIRS AND FIXED LADDERS 1 STAIR CLIMBING It is a fact that only two point contact is possible when we walk normal taking normal steps.

83 STAIRS AND FIXED LADDERS 2 STAIR CLIMBING Just think about it! When you are climbing up or down stairs and not using the hand rails, every time you lift a foot to take the next step you only have one point contact. Now think again how vulnerable you are being in a hurry, running down stairs with your hands filled with what ever you have in them.

84 STAIRS AND FIXED LADDERS 3 STAIR CLIMBING AS FAR AS REASONABLY PRACTICABLE MAINTAIN AT LEAST A THREE POINT CONTACT when climbing up or down any stairs.

85 STAIRS AND FIXED LADDERS 4 Fixed Ladders Any person intending to use a fixed ladder must as far as reasonably practicable: Visually check the condition of the ladder prior to use (climbing) and continuously during use.

86

87

88 STAIRS AND FIXED LADDERS 5 Fixed Ladders Maintain three point contact at all times Carrying tools in an approved and safe manner that does not interfere with you maintaining a three point contact while using the ladder.

89 STAIRS AND FIXED LADDERS 6 Fixed Ladders Ensure that a safe and approved method is used for the raising and lowering of equipment and /or heavy tools from one landing to the following where work is carried out on an elevated platform that is accessed by means of a fixed ladder.

90 SAFE WORK REQUIREMENTS PERTAINING TO FLOOR OPENINGS

91 FLOOR OPENINGS 1 Where guardrails or floor opening covers are temporarily removed, the area into which persons could fall must be: Demarcated with Yellow and Black striped barrier tape. As far as is reasonably practicable a person must be on guard to prevent persons from entering this hazardous area.

92 FLOOR OPENINGS 2 All temporary floor openings that are required to be open for more than 24 hours must be guarded by: Hard barricading with appropriate signage or, By means of Yellow and Black striped barrier tape with a person in attendance to prevent inadvertent entry into the danger zone.

93 FLOOR OPENINGS If you are unsure what hard barricading or signage to use, ask your Foreman or Supervisor to inform and assist you

94 SAFE WORK REQUIREMENTS PERTAINING TO PORTABLE LADDERS

95 PORTABLE LADDERS 1 PORTABLE LADDERS REFER TO Straight ladders Extension and Single Step or A frame ladders Trestle Ladders Stage ladder or platform ladders

96 PORTABLE LADDERS 2 Standard Pre Conditions for using any portable ladder. Conduct a Pre-Work HIRA Before you use any portable ladder first inspect it visually if you find any defects, DO NOT USE that ladder. Report the results as part of your Pre Work HIRA

97 PORTABLE LADDERS 3 Pre Conditions (cont) No Metal ladder my be used in the Anglo Platinum Smelters. No Person may be alone when working on a ladder

98 PORTABLE LADDERS 4 Pre Conditions (cont) Before using any ladder check the soles of your safety boots / shoes and ensure that it is not slippery due to excessive wear or contaminated with oil, grease, liquid detergent, mud, etc

99 PORTABLE LADDERS 5 Importance of maintaining awareness while working on a ladder. Three point contact should always be maintained while climbing up or down a ladder Maintain a safe footing and posture at all times, especially in the case of side reaching Over reaching must be avoided by ensuring that side reaching never places any portion of your body frame excluding your arms but including your shoulders outside the vertical planes of the ladder stiles

100 PORTABLE LADDERS 6 Importance of maintaining awareness while working on a ladder. (Cont) A person standing on a ladder should never exert a force against or from another fixed object, sufficient to create a counter force that could destabilize his ladder. Causing it to fall. This is particularly important when exerting a side force such as pushing or pulling against a spanner situated outside of the vertical plane of the ladder s stiles.?

101 PORTABLE LADDERS 7 Importance of maintaining awareness while working on a ladder. (Cont) The counter forces of a heavy sledge hammer swung onto a solid object could destabilize the safe posture or footing of a worker on a ladder. Only use a light tool hammer when working from a ladder. Every person using a portable ladder must avoid fatigue and loss of awareness of the importance of maintaining a safe footing and work posture by taking short breaks. If the work was planed to take longer than 30 minutes continuously on the ladder. An alternative work platform must be used e.g.. Scaffold, Ladder stage, etc.

102 PORTABLE LADDERS 8 Importance of maintaining awareness while working on a ladder. (Cont) If found that alternative methods for providing access at the required height are not practicable or possible, the following arrangement will then apply: The person on the ladder should time him self so that a short break is taken every 30 minutes for approximately five minutes. He or she should not spend more than 30 minutes working from a ladder for any continuous period. It is important to avoid being overcome by fatigue by maintaining an adequate intake of liquids. During the 5 minute breaks. Drink between 100ml to 300ml of water during hot and humid weather conditions.

103 PORTABLE LADDERS 9 The use of portable ladders must be restricted to providing work access where: If it was found that alternative methods for providing access at the require height are not practicable or possible. A pre work HIRA has been carried out to identify the hazards and control the risks associated with the work to be done from the ladder. The pre work HIRA must always consider the support /loading requirements of the equipment being worked on, the duration of the required work and alternative to using a ladder. ( Including trestle ladders) where practicable.

104 PORTABLE LADDERS 10

105 PORTABLE LADDERS 11 Extension or single (straight) ladders should as far as reasonably practicable, only be used as a means of access or egress from a work area Each portable extension or single (straight) ladder must be examined before use by the person who intends using it. If any damage or other defects are found, DO NOT USE IT

106 Portable Ladders 12 Extension or single (straight) ladders Any portable extension or single (straight) ladder must be set up on a surface that is solid and stable in a manner that will prevent the ladder from slipping

107 Portable Ladders 13 Extension or single (straight) ladders Slipping of portable extension or single (straight) ladders can be prevented by: Placing the straight ladders at a slope op 4 to 1 Ensuring that the ladder is secured at the top and feet. Never placing or resting upper section of the ladder against glass or any other surface that can give way

108 ?

109 ? Portable Ladders 14 Step or A-frame step ladders Step ladders may only be used in the fully open position and a person may not carry out work, climb step or stand in a position higher than the third rung from the top of the ladder. Only light work may be carried out while standing on a step ladder.

110 Portable Ladders 15 Step or A-frame step ladders Each step ladder must be examined before use by the person intending to use it. The ladder MAY NOT be used if any damage or other defects were found. Each step ladder must be set up on a surface that is solid and stable in a manner that will eliminate any instability of the step ladder while in use.

111 Portable Ladders 15 Trestle Ladders Work may not be performed from the work platform of a trestle ladder unless the trestle ladder has edge protection, regardless of the height. Trestle ladders may only be used in their fully open position.

112 Portable Ladders 16 Trestle Ladders Each trestle ladder must be examined before use by the person intending to use it. The ladder MAY NOT be used if any damage or other defects were identified. Each trestle ladder must be set up on a surface that is solid and stable in a manner that will eliminate any instability of the trestle ladder while in use.
