1. INTRODUCTION

Managing the safety of walking and working surfaces is an essential part of any job. A properly safeguarded work environment contributes toward safe execution of work. This Standard describes the minimum requirements for managing the walking and working surfaces within Q-Chem facilities.

2. SCOPE & PURPOSE

This Standard is applicable to all walking and working surfaces inside all Q-Chem operated facilities. The Standard is applicable to:

i. Floor and Wall openings ii. Fixed stairs iii. Fixed platforms iv. Scaffolding

3. DEFINITIONS

eSOMS - Electronic Shift Operations Management System is a mission-critical software used to ensure the safe, efficient, and reliable operation and maintenance of facilities and assets.

Floor Hole - An opening measuring less than 12 inches but more than 1 inch in its least dimension, in any floor, platform, pavement, or yard, through which materials but not persons may fall; such as a belt hole, pipe opening, or slot opening.

Floor Opening - An opening measuring 12 inches or more in its least dimension, in any floor, platform, pavement, or yard through which persons may fall; such as a hatchway, stair or ladder opening, pit, or large manhole. Floor openings occupied by elevators, dumb waiters, conveyors, machinery, or containers are excluded from this subpart.

Handrail - A single bar or pipe supported on brackets from a wall or partition to provide a continuous handhold for persons using a stair.

Ladders - A ladder is an appliance usually consisting of two side rails joined at regular intervals by crosspieces called steps, rungs, or cleats, on which a person may step in ascending or descending.

Pitch - Pitch is the included angle between the horizontal and the ladder, measured on the opposite side of the ladder from the climbing side.

Platform - A working space for persons, elevated above the surrounding floor or ground; such as a balcony or platform for the operation of machinery and equipment.

Scaffold - Any temporary elevated platform and its supporting structure used for supporting workers or materials or both to perform temporary jobs.

Skid - A platform or divider for stacking goods and materials. Stair Railing - A handhold similar to a standard stair railing that is installed in parallel with the

rise of a set of stairs. Stair railings must be fixed at a height of between 30 and 34 inches above the stair tread.

Stair Railing - A vertical barrier erected along exposed sides of a stairway to prevent falls of persons.


Rev. 6


of 15


Stairs - A series of steps leading from one level or floor to another, or leading to platforms, pits, boiler rooms, crossovers, or around machinery, tanks, and other equipment that are used more or less continuously or routinely by employees, or only occasionally by specific individuals. A series of steps and landings having three or more risers constitutes stairs or stairway.

Standard - A standard which requires conditions, or the adoption or use of one or more practices, means, methods, operations, or processes, reasonably necessary or appropriate to provide safe or healthful employment and places of employment.

Standard Railing - A vertical barrier erected along exposed edges of a floor opening, wall opening, ramp, platform, or runway to prevent falls of persons.

Toe board - A vertical barrier at floor level that is erected along exposed openings, such as a floor opening, platform, or runway. Toe boards prevent objects such as tools and materials from falling from one level to the next.

Trapdoor - A floor or ceiling opening that leads to the level above or below. Wall Hole - An opening less than 30 inches but more than 1 inch high, of unrestricted width,

in any wall or partition; such as a ventilation hole or drainage scupper. Wall Opening - An opening at least 30 inches high and 18 inches wide, in any wall or partition,

through which persons may fall; such as a yard-arm doorway or chute opening.

i. All unprotected sides or edges of walking and working surfaces, floors, platforms, ladder way openings, roofs, and holes presenting a fall hazard of four feet (1.2 meters) or greater to a lower level, shall be protected by appropriate guardrail systems. Every ladder-way floor opening or platform shall be guarded by a standard railing on all exposed sides (except at the entrance to the opening) with the passage through the railing either provided with a swing gate or so offset that a person cannot walk directly through the opening.

ii. Where guarding for floor openings, work platforms, or other structures is not possible, employees shall use an appropriate fall arrest system.

4.2. Floors and Floor Openings

ii. Drainage, false floors, platforms or mats shall be provided when dry floors cannot be maintained.

iii. Floors and passageways shall be free from protruding hazards, splinters, holes or loose flooring.

iv. It is prohibited to overload any floor or roof of a building or applicable structure. v. Any work that requires the opening of a walking or working surface (floor boards, grating,

4.3. Heavy Duty Vehicular Access

i. Regular heavy duty vehicle access to each unit /area shall be routed through the ‘Heavy Duty’ grating only. The area demarking / restriction shall be established by either of the following methods: a) Method 1: Routine heavy duty vehicle access to each unit shall be identified and provided

with heavy duty grating. These identified access routes shall be demarked by Black and White stripes and stencilled with “Vehicle Access” wordings as per the following drawing.

b) Method 2: Light duty grating adjacent to ‘Routine heavy duty vehicle access’ (where a

vehicle can run over light duty grating) shall be barricaded with barricade poles and safety sign.

Safety Sign:

Access to the unit apart from the identified “Vehicle Access” routes must be managed

by careful hazard assessment based on the requirement, access location and applied loads.
