B. Staff stress and security

The device shall remain closed at all lower pressures. This requirement does not prevent the use of vacuum relief or combination pressure relief and vacuum relief devices.

6.6.4.7.3 Under the circumstances described in 6.6.4.7.1 and 6.6.4.7.2 together with complete fire engulfment the combined capacity of all pressure relief devices installed shall be sufficient to limit the pressure in the shell to the test pressure.

The more global the world economy becomes, the greater the pressures on firms to globalize.

The cabin will depressurise and we'll be sucked into outer space together.

6.6.3.8.1 The combined delivery capacity of the relief devices shall be sufficient that, in the event of total fire engulfment, the pressure (including accumulation) inside the shell does not exceed 120 of the MAWP.

6.6.2.8.2 Pressure relief devices shall be designed to prevent the entry of foreign matter, the leakage of liquid and the development of any dangerous excess pressure.

6.6.2.12.2 The combined delivery capacity of the relief devices in condition of complete fire engulfment of the portable tank shall be sufficient to limit the pressure in the shell to 20 above the start to discharge pressure of the pressure limiting device.

Security was an issue of paramount importance.

Sir, I must insist. In this case, urgency overrides security.

Her blood pressure was an alarming 230 over 170.

Pressure relief devices shall operate at pressures determined according to both the properties of the organic peroxide and the construction characteristics of the portable tank.

6.6.2.5.10 The burst pressure of all piping and pipe fittings shall be not less than the highest of four times the MAWP of the shell or four times the pressure to which it may be subjected in service by the action of a pump or other device (except pressure relief devices).
