SAFETY INFORMATION
• Installation
GUARDS AND GUARDING
Interfacing of Equipment. When two or more pieces of equipment are interfaced,
special attention shall be given to the interfaced area to ensure the presence
of adequate guarding and safety devices. Guarding Exceptions. Whenever
conditions prevail that would require guarding under these standards, but such
guarding would render the conveyor unusable, prominent warning means shall be
provided in the area or on the equipment in lieu of guarding. Guarded by
Location or Position. Where necessary for the protection of employees from
hazards, all exposed moving machinery parts that present a hazard to employees
at their work station shall be mechanically or electrically guarded, or
guarded by location or position.
- Remoteness from frequent presence of public or employed personnel shall constitute guarding by location.
- When a conveyor passes over a walkway, roadway, or work station, it is considered guarded solely by location or position if all moving parts are at least 8 ft. (2.44 m) above the floor or walking surface or are otherwise located so that the employee cannot inadvertently come in contact with hazardous moving parts.
- Although overhead conveyors may be guarded by location, spill guards, pan guards, or equivalent shall be provided if the product may fall off the conveyor for any reason and if personnel would be endangered.
HEADROOM
- When conveyors are installed above exit passageways, aisles, or corridors, there shall be provided a minimum clearance of 6 ft. 8 in. (2.032 m) measured vertically from the floor or walking surface to the lowest part of the conveyor or guards.
- Where system function will be impaired by providing the minimum clearance of 6 ft. 8 in. (2.032 m) through an emergency clearance, alternate passageways shall be provided.
- It is permissible to allow passage under conveyors with less than 6 ft. 8 in. (2.032 m) clearance from the floor for other than emergency exits if a suitable warning indicates low headroom.
• Operation
A) Only trained employees shall be permitted to operate conveyors. Training
shall include instruction in operation under normal conditions and emergency
situations.
B) Where employee safety is dependent upon stopping and/or starting devices,
they shall be kept free of obstructions to permit ready access.
C) The area around loading and unloading points shall be kept clear of
obstructions which could endanger personnel.
D) No person shall ride the load-carrying element of a conveyor under any
circumstances unless that person is specifically authorized by the owner or
employer to do so. Under those circumstances, such employee shall only ride a
conveyor which incorporates within its supporting structure platforms or
control stations specifically designed for carrying personnel. Under no
circumstances shall any person ride on any element of a vertical conveyor.
E) Personnel working on or near a conveyor shall be instructed as to the
location and operation of pertinent stopping devices.
F) A conveyor shall be used to transport only material it is capable of
handling safely.
G) Under no circumstances shall the safety characteristics of the conveyor be
altered if such alterations would endanger personnel.
H) Routine inspections and preventive and corrective maintenance
“Building Relationships One Conveyor Part at a Time”
programs shall be conducted to ensure that all safety features and devices are
retained and function properly.
I) Personnel should be alerted to the potential hazard of entanglement in
conveyors caused by items such as long hair, loose clothing, and jewelry.
J) Conveyors shall not be maintained or serviced while in operation unless
proper maintenance or service requires the conveyor to be in motion. In this
case, personnel shall be made aware of the hazards and how the task may be
safely accomplished.
K) Owners of conveyor should ensure proper safety labels are affixed to the
conveyor warning of particular hazards involved in operation of their
conveyors.
CAUTION! Because of the many moving parts on the conveyor, all personnel
in the area of the conveyor need to be warned that the conveyor is about to be
started.
• Maintenance
- All maintenance, including lubrication and adjustments, shall be performed only by qualified and trained personnel.
- It is important that a maintenance program be established to ensure that all conveyor components are maintained in a condition which does not constitute a hazard to personnel.
- When a conveyor is stopped for maintenance purposes, starting devices or powered accessories shall be locked or tagged out in accordance with a formalized procedure designed to protect all persons or groups involved with the conveyor against an unexpected start.
- Replace all safety devices and guards before starting equipment for normal operation.
- Whenever practical, DO NOT lubricate conveyors while they are in motion. Only trained personnel who are aware of the hazard of the conveyor in motion shall be allowed to lubricate.
Safety Guards
Maintain all guards and safety devices IN POSITION and IN SAFE REPAIR.
Safety Labels
In an effort to reduce the possibility of injury to personnel working around
HYTROL conveying equipment, safety labels are placed at various points on the
equipment to alert them of potential hazards. Please check equipment and note
all safety labels. Make certain your personnel are alerted to and obey these
warnings. See Safety Manual for examples of warning labels.
REMEMBER Do not remove, reuse, or modify material handling equipment for any
purpose other than its original intended use.
INSTALLATION
• Conveyor Set-Up
-
Determine direction of product flow. The drive is located at the discharge end of the Model SBC. See Figure 4A.
-
Position conveyor in sequence per match-mark numbers at each end.
-
Attach supports as show in Figure 4B. Adjust elevation to required height.
NOTE: If celing hangers are used, see Ceiling Hangers section. -
Install electrical controls and wire motor.
Ceiling Hanger Installation
If conveyors are to be used in an overhead application, ceiling hangers may
have been supplied in place of floor supports. Figure 4C shows how a ceiling
hanger mounts to a conveyor section. Ceiling hangers should be mounted at
section joints. Ceiling Hanger Rod needs to be a minimum of 3″ from the
inside channel. For safety information concerning conveyors mounted overhead,
refer to “Installation Safety Precautions” on Page 3.
• Electrical Equipment
WARNING! Electrical controls shall be installed and wired by a qualified
electrician. Wiring information for the motor and controls are furnished by
the equipment manufacturer.
CONTROLS
Electrical Code: All motor controls and wiring shall conform to the National
Electrical Code (Article 670 or other applicable articles) as published by the
National Fire
Protection Association and as approved by the American Standards Institute,
Inc.
CONTROL STATIONS
A) Control stations should be so arranged and located that the operation of
the equipment is visible from them, and shall be clearly marked or labeled to
indicate the function controlled.
B) A conveyor which would cause injury when started shall not be started until
employees in the area are alerted by a signal or by a designated person that
the conveyor is about to start.
When a conveyor would cause injury when started and is automatically
controlled or must be controlled from a remote location, an audible device
shall be provided which can be clearly heard at all points along the conveyor
where personnel may be present. The warning device shall be actuated by the
controller device starting the conveyor and shall continue for a required
period of time before the conveyor starts. A flashing light or similar visual
warning may be used in conjunction with or in place of the audible device if
more effective in particular circumstances.
Where system function would be seriously hindered or adversely affected by the
required time delay or where the intent of the warning may be misinterpreted
(i.e., a work area with many different conveyors and allied devices), clear,
concise, and legible warning shall be provided. The warning shall indicate
that conveyors and allied equipment may be started at any time, that danger
exists, and that personnel must keep clear. The warnings shall be provided
along the conveyor at areas not guarded by position or location.
C) Remotely and automatically controlled conveyors, and conveyors where
operator stations are not manned or are beyond voice and visual contact from
drive areas, loading areas, transfer points, and other potentially hazardous
locations on the conveyor path not guarded by location, position, or guards,
shall be furnished with emergency stop buttons, pull cords, limit switches, or
similar emergency stop devices.
All such emergency stop devices shall be easily identifiable in the immediate
vicinity of such locations unless guarded by location, position, or guards.
Where the design, function, and operation of such conveyor clearly is not
hazardous to personnel, an emergency stop device is not required.
The emergency stop device shall act directly on the control of the conveyor
concerned and shall not depend on the stopping of any other equipment. The
emergency stop devices shall be installed so that they cannot be overridden
from other locations.
D) Inactive and unused actuators, controllers, and wiring should be removed
from control stations and panel boards, together with obsolete diagrams,
indicators, control labels, and other material which serve to confuse the
operator.
SAFETY DEVICES
A) All safety devices, including wiring of electrical safety devices, shall be
arranged to operate in a “Fail-Safe” manner, that is, if power failure or
failure of the device itself would occur, a hazardous condition must not
result.
B) Emergency Stops and Restarts. Conveyor controls shall be so arranged that,
in case of emergency stop, manual reset or start at the location where the
emergency stop was initiated, shall be required of the conveyor(s) and
associated equipment to resume operation.
C) Before restarting a conveyor which has been stopped because of an
emergency, an inspection of the conveyor shall be made and the cause of the
stoppage determined. The starting device shall be locked out before any
attempt is made to remove the cause of stoppage, unless operation is necessary
to determine the cause or to safely remove the stoppage.
Refer to ANSI Z244.1-1982, American National Standard for Personnel Protection
– Lockout/Tagout of Energy Sources – Minimum Safety Requirements and OSHA
Standard Number 29 CFR 1910.147 “The Control of Hazardous Energy (Lockout/
Tagout).”
OPERATION
- Only trained employees shall be permitted to operate conveyors. Training shall include instruction in operation under normal conditions and emergency situations.
- Where employee safety is dependent upon stopping and/or starting devices, they shall be kept free of obstructions to permit ready access.
- The area around loading and unloading points shall be kept clear of obstructions which could endanger personnel.
- No person shall ride the load-carrying element of a conveyor under any circumstances unless that person is specifically authorized by the owner or employer to do so. Under those circumstances, such employee shall only ride a conveyor which incorporates within its supporting structure, platforms or control stations specifically designed for carrying personnel. Under no circumstances shall any person ride on any element of a vertical conveyor. Owners of conveyors should affix warning devices to the conveyor reading. Do Not Ride Conveyor.
- Personnel working on or near a conveyor shall be instructed as to the location and operation of pertinent stopping devices.
- A conveyor shall be used to transport only material it is capable of handing safety.
- Under no circumstances shall the safety characteristics of the conveyor be altered if such alterations would endanger personnel.
- Routine inspections and preventive and corrective maintenance programs shall be conducted to insure that all safety features and devices are retained and function properly.
- Personnel should be alerted to the potential hazard of entanglement in conveyors caused by items such as long hair, loose clothing, and jewelry.
- As a general rule, conveyors should not be cleaned while in operation. Where properly cleaning requires the conveyor to be in motion and a hazard exists, personnel should be made aware of the associated hazard.
• Conveyor Start-Up
Before conveyor is turned on, check for foreign objects that may have been
left inside the conveyor during installation. These objects could cause
serious damage during start-up.
After conveyor has been turned on and is operating, check motors, reducers,
and moving parts to make sure they are working freely.
MAINTENANCE
- Maintenance, such as lubrication and adjustments, shall be performed only by qualified and trained personnel.
- It is important that a maintenance program be established to insure that all conveyor components are maintained in a condition which does not constitute a hazard to personnel.
