Process Safety Management of Highly Hazardous & Explosive Chemicals

1. Process Safety Management
of Highly Hazardous &
Explosive Chemicals
Operating Procedures, Safety Procedures &
Training

2. Now that the PHA’s Are
Competed or Underway…
Operating
Procedures & Safety
Programs Must Be
Developed
PHA Information
Can Be Used

3. Operating Procedures
1910.119(f)

4. Operating Procedures & Safety
Programs Must Consider:
Initial start-up
Normal operations
Temporary operations
Emergency shutdown
Emergency operations
Normal shutdown
Start-up following turnaround
Consequences of deviation
Steps required to correct or avoid deviation

5. Operating Procedures or
Standard Operating Procedures
(SOP’s)
Where Did This Methodology Come From?
Answer: The Military
Definition: A standard operating procedureis a set
of instructions having the force of a directive,
covering those features of operations that lend
themselves to a definite or standardized procedure
without loss of effectiveness. Standard Operating
Policies and Procedures can be effective catalysts to
drive performance improvement and improving
organizational results. Every good quality system is
based on its standard operating procedures (SOPs).

6. *Readily accessible to employees
Operating Procedures
Develop and implement written operating procedures*
consistent with the process safety information and addresses
at least the following elements:
Initial start-up, normal and temporary operations
Normal and emergency shut-down procedures
Operating limits and consequences of deviation
Hazards presented by the process

7. Operating Procedures
The operating procedures addressing
operating parameters will contain operating
instructions about:
pressure limits
temperature ranges
flow rates…and
what to do when an upset condition occurs
what alarms and instruments are pertinent if an
upset condition occurs, and other subjects.

8. Operating Procedures -Start
Up…We Must
Describe normal SOP's
Describe start-up SOP's
Describe Shut-down
SOP’s

9. Include Sections such as:
Objectives
Purpose
Concerns
Procedures
Department
Operator
Equipment Involved

Operating Procedures -Start
Up…We Must
Let’s Look at An Example…

10. Objective This procedure is designed to describe the Technical Operating
Specifications (TOS), and to set down the Standard Operating
Procedures for the safe operation of Ammonia High Pressure
Receiver 1 (HPR-1)
Purpose: The purpose of the TOS is to provide a description of the High
Pressure Receiver, to define the function of the receiver, its
operating conditions and limits, and consequences of deviation
from these limits; To describe controls and instrumentation and
safety systems, and set operating alignments.The purpose of
the Standard Operating Procedure (SOP) is to set down the
proper steps for starting, monitoring normal operation, and
stopping and restarting the Receiver under normal and
emergency conditions
Concerns: Very Careful attention to valve positions, temperature, and
pressure levels is extremely important to the successful
completion of these procedures. Deviations from normal
operating limits could cause personal injury or death, small to
catastrophic release of ammonia or environmental damage, or
evacuation of, or injury to, members of the public. We seek to
prevent incidents such as:
Injury to operators and others in the area. Damage to the High
Pressure Receiver. Release of any quantity of Anhydrous
Ammonia refrigerant.
The company Lockout/Tagout program shall be followed when
taking the receiver out of service, while maintaining the
receiver, and while returning it to service. If Line-Breaking is
required, all Line-Breaking precautions described in the
company Line-Break Policy shall be observed. Additionally,
proper PPE shall be immediately available, or worn in response
to the threat level posed by the work and circumstances.
