Disintegrator Safety Rules

 

1. 

Read entire manual prior to installation or initial operation.  

2. 

Observe and follow your company’s safety policy regarding disintegrating equipment.

 

3. 

MOVING OR LIFTING THE DISINTEGRATOR

: Care must be taken when moving the machine along the floor or 

when lifting it. Damage may occur to sheet metal covers, electrical cabinets, or small brackets if pressure is 

applied to them when moving the disintegrator. When lifting the disintegrator, be certain of total machine 

weight and the capability of the lifting equipment. 

4. 

Always disconnect and perform lockout tagout (LOTO) when disconnecting the main electrical power to the 

disintegrator before performing any service. 

5. 

SAFETY INTERLOCKS MUST NOT BE BYPASSED

. The mechanical and electrical safety interlocks ensure the 

safety of personnel. They should never be tampered with or removed for ANY reason. They should be frequently 

checked by a qualified mechanic for proper operation. 

6. 

DISINTEGRATOR LOCATION

: Provide an adequate area for routine maintenance that allows machine to 

be opened for service.  

7. 

SAFE HOUSEKEEPING:

 The work area should be kept clean and uncluttered to allow personnel safe 

movement around the disintegrator during periods of operation or maintenance. No hand or power tools should 

be left on or about the machine. Any tools or other metal objects which mistakenly fall into the hopper feed 

opening can cause severe damage to internal screen chamber and cutting chamber components. 

8. 

SAFETY GLASSES OR A FACE SHIELD MUST ALWAYS BE WORN

 when operating or servicing the machine. 

Although SEM machines are designed for the maximum in fly back control, caution must be used when 

operating near the area of the hopper feed opening in order to guard against unexpected material fly back. 

9. 

EAR PROTECTION

 may be required when operating the machine during disintegration of very hard/noisy materials. 

The Occupational Safety and Health Act of 1970 (OSHA) has established guidelines for permissible noise 

exposures (1910.95) that should be followed. Each site should determine their own requirements for PPE. 

10. 

NEVER

 operate the disintegrator unless it is fully assembled with all guards and interlocks in place and functional. 

11. 

Observe all danger, warning, caution, and safety labels on the equipment. 

12. 

Upon completion of any machine maintenance, be certain all safety guards and covers

 

are securely and 

properly fastened prior to resuming machine operation. Failure to secure and tighten all safety guards and 

covers may result in injury to personnel and equipment.  

13. 

NEVER

 wear any loose fitting clothes, neckties, or dangling items such as earrings, belts, or shoestrings. Jewelry 

such as wristwatches, bracelets, or rings should 

NEVER

 be worn. Long hair must be tied back or placed 

within a tight fitting hairnet. 

NEVER

 lean against or rest hands/feet on the disintegrator when it is in operation 

or opened for maintenance. 

NEVER

 stand on the disintegrator when it is in operation. 

14. 

ROTATION OF MOTORS:

 All rotating items in the disintegrator are clearly marked on the machine. Always check 

for proper rotation of motors. 

15. 

ELECTRICAL GROUNDING:

 All electrical equipment on the disintegrator must be grounded in accordance to 

all local codes and Article 250 of the National Electric Code. 

16.

  NEVER 

modify the machine configuration or any individual component.
