SCAFFOLDS

INTRODUCTION

The Occupational Safety and Health Act under 29 CFR 1926 Subpart L establishes requirements

to address the hazards associated with the use of scaffolding. In response to the regulatory

mandate Steingass Mechanical Contracting, Inc. has developed and will maintain the Scaffolding

Program to provide the proper and safe procedures for all applicable employees.

PURPOSE

This document is primarily intended to outline the methods of protecting and/or informing all

employees engaged in the use of scaffolds. In addition, it is intended that Steingass Mechanical

Contracting, Inc. will be in full compliance with 29 CFR 1926 Subpart L.

Due to the serious nature of this policy, Steingass Mechanical Contracting, Inc. intends to

continually monitor this policy for its workability and identify inadequacies or deficiencies.

RESPONSIBILITY

Steingass Mechanical Contracting, Inc. shall instruct all applicable employees in the safety

significance of the Scaffold Program and/or procedures. In addition, Steingass Mechanical

Contracting, Inc. considers these requirements to be of critical importance in helping to ensure

that the applicable provisions of the Scaffold Program are known, understood, and strictly

adhered to by all employees. Strict enforcement of this program is required as a condition of

employment. Any variations from these set procedures will be considered a work rule violation

and because of the serious nature of this program, disciplinary action will be taken in accordance

with the disciplinary guidelines described in Steingass Mechanical Contracting, Inc. Safety Rules

and Regulations.

Plan Prepared By:

Plan Approved By:

Plan Supervised By:

Steingass Mechanical Contracting, Inc. is dedicated to the protection of its employees from on-

the-job injuries. All employees of Steingass Mechanical Contracting, Inc. have the responsibility

to work safely on the job. The purpose of this plan is to supplement our existing safety and

health program and to ensure that every employee recognizes workplace fall hazards and takes

the appropriate measures to address those hazards.

This Fall Protection Plan supports the use of conventional fall protection when it is clearly

beneficial to the erector. During the erection / dismantling of scaffolds, it is often unfeasible or a

creates a greater hazard to use conventional fall protection systems during the different phases,

which include, but are not limited to:

a. Setting and bracing of scaffold frames and other components;

b. Installation of planking and deck sheathing.

In those cases, which would create a greater hazard for the erectors, conventional fall protection

systems must be not be used. This plan is designed to enable the erectors to recognize the fall

hazards associated with this project and to establish the safest procedures that are to be followed

in order to reduce those hazards and prevent falls.

CONTROLLED ACCESS ZONES

When utilizing this plan to implement the fall protection options available, employees

must be protected through limited access to high hazard locations. Before any non-

conventional fall protection systems are used as part of the work plan, a controlled access

zone (CAZ) will be clearly defined by the competent person as an area where a

recognized hazard exists.

The competent person will communicate the demarcation of the CAZ in a recognized

manner, either through signs, types, ropes or chains. Steingass Mechanical Contracting,

Inc. will take the following steps to ensure that the CAZ is clearly marked or controlled

by the competent person:

All access to the CAZ must be restricted to authorized entrants;

All employees who are permitted in the CAZ will be listed in the appropriate

sections of the Plan and be visibly identifiable by the competent person prior

to implementation;

The competent person will ensure that all protective elements of the CAZ be

implemented prior to the beginning of work.

INSTALLATION PROCEDURES FOR THE SCAFFOLD FRAMES,

CROSS BRACES, PLANKS, DECKING AND ALL

OTHER SCAFFOLD COMPONENTS

Conventional fall protection may present a greater hazard to employees. On this job, the

use of personal fall arrest systems will not provide adequate fall protection because there

are no anchorage points for personal fall arrest systems. On this job, requiring the

erectors to attach their personal fall arrest systems to the scaffolding below them will

create a tripping hazard. In addition, the scaffold does not provide an adequate anchorage

point (5,000 lbs.) and requiring the erectors to attach to the scaffold will give them a false

sense of security.

Steingass Mechanical Contracting, Inc. will take the following steps to protect erectors

who are exposed to fall hazards while working from the scaffold frames and the

incomplete work platforms:

Only the following trained employees will be allowed to work on the

incomplete scaffold system installation:

Employees will have no other duties to perform during scaffold erection

procedures;

the entire scaffold frames will be adequately braced before any worker can use

them as a support;

Employees will remain on the previously stabilized scaffold frames / planks as

a support while the other frames / planks are being erected;

Erectors will leave the area of the secured frames only when it is necessary to

secure another frame;

Once scaffold erection installation beings, employees not involved in that

activity will not stand or walk below or adjacent to the scaffold system being

erected or in any area where they could be struck of falling objects;

Employees will not remain on the scaffold system longer than necessary to

safely complete the task.

When strong winds (above 40 miles per hour) are present, erection operations

of frames, bracing, planks and all other components are to be suspended.

DECK SHEATHING INSTALLATION OPERATIONS

Employees typically install the frames, all the joists and required bracing before the

sheathing is installed. To minimize the time erectors must be exposed to a fall hazard,

materials will be staged to allow for the quickest installation of sheathing.

Steingass Mechanical Contracting, Inc. will take the following steps to protect employees

who are exposed to fall hazards while installing deck sheathing:

Only the following trained employees will be allowed to work on the

incomplete scaffold system installation:

Once deck sheathing installation beings, employees not involved in that

activity will not stand or walk below or adjacent to the scaffold system or

in any area where they could be struck by falling objects;

The competent person will determine the limits of this area, which will be

clearly communicated to employees prior to placement of the first piece of

deck sheathing;

The competent person may order work on the deck to be suspended for

brief periods as necessary to allow other employees to pass through such

areas when this would not create a greater hazard;

Any employees not assisting in the leading edge construction while

leading edges still exist (i.e. cutting the decking for the installers) will not

be permitted within six feet of the leading edge under construction.

Materials for operations will be conveniently staged to minimize fall

hazards;

When wet weather (rain, snow or sleet) is present, deck sheathing

operations will be suspended unless safe footing can be assured for those

employees installing sheathing.

When strong winds (above 40 miles per hour) are present, deck sheathing

operations are to be suspended.

ENFORCEMENT

Constant awareness of and respect for fall hazards and compliance with all safety rules are

considered conditions of employment. The foreman has the total authority to stop the progress

of the project until all unsafe conditions have been corrected. Management reserves the right to

issue disciplinary warnings to employees, up to and including termination, for failure to follow

the guidelines of this program.

ACCIDENT INVESTIGATIONS

All accidents that result in injury to employees, regardless of their nature, will be reported and

investigated. It is an integral part of any safety program that documentation takes place as soon

as possible so that the cause and means of prevention can be identified to prevent a recurrence.

In the event that an employee falls and there is some other related, serious incident occurring,

this Plan will be reviewed to determine if additional practices, procedures or training need to be

implemented to prevent similar types of falls or incidents from occurring.

CHANGES TO PLAN

Any changes to the plan will be approved by _________________________________________

Name/Title

A qualified person will review this plan as the job progresses to determine if additional practices,

procedures or training needs to be implemented by the competent person to improve additional

fall protection. Employees will be notified and trained, if necessary, in the new procedures. A

copy of this plan and all approved changes will be posted at the job site.
