2.6 Lock out and tag out procedure Software Version SR.405.xx 05/99 Issue

2.6.4 Responsibilities

1. It shall be the responsibility of the maintenance and electrical personnel to make sure this pro-

cedure is adhered to.

2. It shall be the responsibility of the maintenance and electrical personnel’s immediate

supervisor to instruct his personnel on this procedure.

3. It shall be the responsibility of the Safety Officer with assistance from the Safety Committee,

Health Service Department, and the various managers and Vice-Presidents to administer the

Lock Out / Tag Out Procedure.

2.6.5 Training

1. Employee training

The safety regulations require training for every individual, of course every employee is not ex-

posed to the same degree of danger or is involved with LO/TO as others are. So extensive

training is not necessary for everyone. 2

2. To determine how much training to provide for each worker, the employees are divided into

three groups. Each group has its own level of training.

3. Authorized employees

These workers actually install the locks and tags and do the maintenance or service work. So

they must know the most about controlled energy. First, they must be able to recognize all

energy sources and measure the amount of energy. Authorized employees must look for en-

ergy sources out of the realm of the obvious. These energy sources include electrical, mechan-

ical, hydraulic, pneumatic, chemical, thermal and gravitational. Once these workers can

recognize all energy sources they must be taught how to isolate, control, and release the en-

ergy without any risk. 2

4. Affected employees

These are workers who operate the machinery or equipment that may be de-energized. Other

employees who may be affected include those who work in an area that contain equipment that

may be locked/tagged out. These employees have to be instructed about the nature of the en-

ergy control program, they must know why lock/tag out is important, what tags and locks look

like and why they must not remove tags or locks. 2

5. All others

As the name implies, any employee who is not affected or authorized fits into this category.

There employees include office personal, engineers, managers, and upper management. Al-

though they do not have a direct relationship to the machinery being locked or tagged, they

have to receive some training. 2

Software Version SR.405.xx 05/99 Issue 2.6 Lock out and tag out procedure

6. To evaluate the lock/tag out procedure, the safety department will conduct periodic inspec-

tions. As part of the inspection the safety department will document that all facets of the pro-

cedure are followed. The safety department will follow up with formal classroom review or re-

training of the LO/TO procedure.

2.6.6 Review

This procedure will be reviewed and amended as required but in no case less frequently than once

a year. 2

2.6.7 Appendix

These procedures represent the minimum lock/tag out requirements. Any additional safeguards

needed to complete work safely can be specified by facilities supervision, the safety officer, the

safety committee and the health department. 2

2.7 Emissions and energy efficiency of the MCM 1405 ND monitor Software Version SR.405.xx 05/99 Issue

2.7 Emissions and energy efficiency of the MCM 1405

ND monitor

2.7.1 X-ray radiation

The X-ray radiation generated in the monitor is adequately shielded by the intrinsically safe cath-

ode-ray tube. The local emissions are less than 1

S/h (micro-Sievert per hour). The accelerating

voltage is limited by the device to a maximum of 26 kV. 2

The monitor conforms to the German Directive for protection against harmful X-ray radiation. The

X-ray emissions from the monitor conformed to the DHHS Rules 21 CFR, subsection J on the date

of manufacture and to the FCC Rules, part 15. 2

2.7.2 Efficiency and electromagnetic emissions

The MCM 1405 ND monitor fulfils the conditions for efficiency (to ISO 9241-3) and safety (to EN

60950). 2

The low-frequency electromagnetic emissions fall below the MPR II guidelines issued by the

Swedish Radiation Institute in Stockholm. 2
