Safety
Safety must be considered a basic factor in machinery operation at all times. Most accidents are the result of
carelessness or negligence. The following safety instructions are basic guidelines and should be considered as minimum
provisions. Additional information shall be obtained by the purchaser from other sources including the latest editions of
American Society of Mechanical Engineers; Standard ANSI B20.1; Standard ANSI B15.1; Standard ANSA A12.1; Standard
ANSI MH4.7; Standard ANSI Z244.1-1982.
It is the responsibility of the contractor, installer, owner, and user to install, maintain and operate the conveyor components
and conveyor assemblies manufactured and supplied by the Conveying Machinery Div., in such a manner as to comply
with the Williams-Steiger Occupational Safety and Health Act, and with all state and local laws and ordinances and the
American National Standard Institute Safety Code.
PRECAUTIONS:
1.
Maintain a safety training and safety equipment operation/maintenance program for all employees.
2.
Screw Conveyors shall not be operated unless the conveyor housing completely encloses the conveyor moving
elements and power transmission guards are in place. If the conveyor is to be opened for inspection,
cleaning or observation, the motor driving the conveyor is to be locked out electrically In such a manner
that it cannot be restarted by anyone, however remote from the area, unless the conveyor housing has
been closed, and all other guards are in place.
3.
If the conveyor must have an open housing as a condition of its use and application, the entire conveyor is then to
be guarded by a railing or fence.
4.
RUGGED gratings may be used where necessary. If the distance between the grating moving elements is less
than 4 inches, the grating opening must not exceed 1/2 inch by 2 inch. In all cases the openings shall be
restrictive to keep any part of the body or clothing from coming in contact with moving parts of the equipment.
SOLID COVERS should, be used at all other points and must be designed and installed so that personnel will not
be exposed to accidental contact with any moving parts of the equipment.
5.
All rotating equipment such as drives, gears, shafts, and couplings must be guarded by the purchaser/owner as
required by applicable laws, standards and good practice.
6.
SAFETY DEVICES AND CONTROLS must be purchased and provided by the purchaser/owner as required by
applicable laws, standards and good practices.
7.
Practice good housekeeping at all times and maintain good lighting around all equipment.
8.
Keep all operating personnel advised of the location and operation of all emergency controls and devices. Clear
access to these controls and devices must be maintained.
9.
Frequent inspections of these controls and devices, covers, guards, and equipment to insure proper working order
and correct positioning must be performed.
10.
Do not walk on conveyor covers, gratings or guards.
11.
Do not poke or prod material in the conveyor.
12.
Do not place hands, feet, or any part of the body or clothing in the conveyor or opening.
13.
Do not overload conveyor or attempt to use it for other than its intended use.
14.
Inlet and discharge openings shall be connected to other equipment in order to completely enclose the conveyor.
15.
Before power is connected to the drive, a pre-startup safety check shall be performed to insure the equipment and
area are safe for operation and all guards are in place and secure.
16.
Screw Conveyors are not normally manufactured or designed to handle materials that are hazardous to personnel.
These materials which are hazardous include those that are explosive, flammable, toxic, or otherwise dangerous
to personnel. Conveyors may be designed to handle these materials. Conveyors are not manufactured or
designed to comply with local, state or federal codes for unfired pressure vessels. If hazardous materials are to
be conveyed and if the conveyor is to be subjected to internal or external pressure, the it Conveyor Division should
be consulted prior to any modifications.
