Emergency Measure

Emergency measures should only be used as a last resort, when runaway cannot be prevented. Thus, they should only be considered after all other approaches have been tried and found to be unsuccessful. [Pg.253]


The maximum allowable oxygen concentration (MAOC), which is, in general, 2 vol % below the LOC, has to include the following considerations fluc tuatiou in oxygen concentrations due to process and breakdown conditions per time and location, as well as the requirement for protective measures or emergency measures to become effective. In addition, a concentration level for an alarm has to be set below the MAOC. [Pg.2323]

A pesticide manufacturing plant should prepare a hazard assessment and operability study and also prepare and implement an emergency preparedness and response plan that takes into account neighboring land use and the potential consequences of an emergency. Measures to avoid the release of harmful substances should be incorporated in the design, operation, maintenance, and management of the plant. Implementation of cleaner production processes and pollution prevention measures can yield both economic and environmental benefits. [Pg.72]

If pronounced bradycardia occurs, the primary heal til care provider may order emergency measures, such as die administration of IV atropine (see Chap. 25) or isoproterenol (see Chap. 22). Any sudden change in mental state should be reported to the primary health care provider immediately because a decrease in die dosage may be necessary. [Pg.377]

The IV solutions of plasma expanders include hetastarch (Hespan), low-molecular-weight dextran (Dextran 40), and high-molecular-weight dextran (Dextran 70, Dextran 75). Plasma expanders are used to expand plasma volume when shock is caused by bums, hemorrhage surgery, and otiier trauma and for prophylaxis of venous thrombosis and diromboembolism. When used in die treatment of shock, plasma expanders are not a substitute for whole blood or plasma, but tiiey are of value as emergency measures until die latter substances can be used. [Pg.635]

New systems or processes may also need to be qualified from an operational safety perspective. This is particularly relevant in the case of chemical synthesis involving exothermic reactions. Critical safety aspects are usually identified using hazard operability or HAZOP assessments and studies. For example, a HAZOP analysis of an exothermic reaction vessel would involve consideration of the consequence of failure of the motors for mixers or circulation pumps for cooling water. Thus, the qualification of such a system would involve checks and assessment to ensure that the system/process can be operated safely and that pressure relief valves or other emergency measures are adequate and functional. [Pg.226]

Emergency measures — including appropriate personal behaviour — to take in the event of an incident. [Pg.294]

A wider spectrum of cover may be obtained, which m be (a) desirable as an emergency measure in life-threatening situations or (b) of use in treating mixed infections. [Pg.128]

In situ methods have potential use as an interim or emergency measure until dredging can be undertaken or as a primary remedial action where it is determined to be more cost-effective than removal. The biggest advantages are that they are much less costly than dredging, eliminate the need for dredged material management, and minimize the resuspension of contained sediments.15... [Pg.641]

Time-to-runaway, described later, is an important parameter in the development of adequate emergency measures. Short times require the use of well-defined operating modes or require completely automated controls. [Pg.99]

The activation logic for and ESD system should be kept as simple at possible. Typically most facilities specify plateaus or levels of ESD activation. These levels activate emergency measures for increasing amounts or areas of the facility as the emergency involves a larger and larger area or the degree of hazard from the initial event. Low hazards or small area involvement would only require a shutdown of individual equipment while major incidents would require a facility shutdown. The shutdown of one of a facility should not present a hazard to another portion of the facility otherwise both should be shut down. Typical levels utilized in the petroleum and related industries are identified in Table 12. [Pg.117]

Both Article 6(1) and Annex VII require notifiers to provide information concerning recommended methods and precautions for safe handling, storage, use, and transport of their substances. Annex VII also specifies that notifications must include emergency measures in the case of "accidental spillage" or "injury to persons (e.g. poisoning). ... [Pg.45]

Before the incident, neither the reaction and decomposition energy potentials nor the triggering conditions of the decomposition were known. Thus, a potentially severe process was entirely under manual control, without provision for an alarm system and emergency measures. A correct assessment of the energies and triggering conditions of the decomposition predicts such an incident, giving the opportunity to design a process that will avoid such incidents. [Pg.59]

The probability can be evaluated using the time-scale If, after the cooling failure (Question 4), there is enough time left (Questions 5 and 6) to take emergency measures before the runaway becomes too fast, the probability of the runaway will remain low. [Pg.66]

If the thermal stability is not sufficient at the MTSR, emergency measures must be taken to avoid a runaway (see Chapter 10). [Pg.141]

A discussion about risk reducing measures is presented in Section 1.3.1.7. When reducing risks linked to a runaway reaction, the same principles apply. Thus, the first priority should be implementing measures that avoid runaways. As as second priority, preventive measures should then be applied, in case a runaway has been triggered. As a last resort, emergency measures should mitigate the consequences of a runaway that cannot be avoided. Of course, the priority is to avoid the problem rather than to solve it [1]. [Pg.243]
