CONTROL RELIABILITY:
“...control circuits shall be designed and constructed so
that a single failure or fault within the system does not
prevent the normal stopping action from being applied
to the press when required, or does not create an
unintended stroking action, but does prevent initiation
of a successive stroke until the failure is corrected.”
(ANSI B11.1-1988)
“...control shall be designed to prevent initiation of a
stroke signal in the event that a failure occurs within the
press control.” (ANSI B11.2-1982)
“Robots shall be designed and constructed so that any
single, reasonably foreseeable failure will not cause
hazardous motion of the robot.” (ANSI/RIA R15.06-
1991)
“...control circuits shall incorporate features to minimize
the possibility of an unintended stroke in the event of
the failure of the control component to function properly,
including relays, limit switches, and static output circuits.”
(ANSI B11.1-1982)
“...control system shall be constructed so that a failure
within the system does not prevent the normal stopping
action from being applied to the press when required,
but does prevent initiation of a successive stroke until
the failure is corrected.” (ANSI B11.1-1982)
“...the control system shall be constructed so that a failure
within the system does not prevent the normal stopping
action from being applied to the press when required,
but does prevent initiation of a successive stroke until
the failure is corrected.” (OSHA CFR 1910.217, 1988)

Operational Safety
1. Appoint a Safety Coordinator to be responsible
for safety regulations, requirements, and
suggestions. He must review and investigate
all accidents and “close calls.”
2. Establish and issue safety rules. Inform each
employee of his responsibilities. Make sure he
understands them and knows what is expected
of him.
3. A thorough review and an early inspection must
be made of existing presses, dies, and point of
operation guarding to attain the degree of
responsibility required by ANSI B11.1-1988
Safety Standards and Federal S tate laws.
Review what mandatory modifications are
necessary.
4. Equipment that is no longer safe and that cannot
be economically upgraded should be destroyed.
5. Never allow persons legally under age to
operate or assist in the operation of machinery.
6. All personnel must be properly trained to
eliminate accidents and injuries.
7. Regardless of the operator ’s experience,
education or language barrier , it is the
responsibility of the supervisor to give him a
thorough explanation with each new job
assignment.
8. No employee should be given a work
assignment that he does not fully understand.
Only properly instructed and thoroughly trained
personnel should be assigned to work on or with
any machine.
9. It shall be the responsibility of the employer to
provide an adequate, clean, safe and
uncluttered work area around each machine.
10. If a malfunction is reported, stop the machine
immediately, correct the problem, then resume
production.
11. Investigate all accident s and close calls.
Analyze the reason for occurrence. Take action
to prevent recurrence. Keep records of the
investigation and preventative steps that were
taken.
12. Only employees who understand the machines,
operation and safety requirements, and who are
able to communicate this knowledge should be
given the responsibility of instructing and training
others to perform as operators.
13. Management must decide that personnel
protective safety equipment is required to
perform each job safely. Items such as safety
glasses, shoes, gloves, helmets, hand pads,
spats, protective sleeves, and material handling
equipment are common in the metal working
industry. If noise levels are excessive, protective
head sets and ear muffs are recommended.
14. When designing point of operation guarding, the
manufacturing process should be weighed
heavily in favor of operational safety.
15. Establish safe and convenient material handling
methods and procedures.
