Pressure plant

Plant designed to contain gas or vapour, such as steam, under pressure. The majority of items have to be inspected under statutory provisions. A steam boiler is an example. The principal risk is explosion and/or collapse.
***

Pressure Systems Safety Regulations 2000

The aim is to prevent injury from the hazard of stored energy due to system failure. Pressure system users/owners must show that they know the safe operating limits, mainly pressure and temperature, of their pressure systems, and that the systems are safe under those conditions. They need to: (a) have a suitable written scheme of examination before the system is operated; (b) ensure that the pressure system is examined in accordance with the written scheme; (c) ensure that the scheme is certified by a competent person.

Pressure vessel

In boiler and machinery insurance, a type of container designed to hold liquids or gasses under pressure. Types are categorized as fired (such as a boiler) and unfired (such as an oxygen or hydrogen tank).
***
A container designed to hold steam, gas or other vapor under pressure.

Presumption of agency

An agency relationship that is legally enforceable, although no agreement has been signed. This presumption of a relationship exists when the insurer acts in a way that gives the idea that someone is his or her agent before the agent has truly been accepted by them; for example, by providing that person with materials bearing the company logo for distribution. The insurer may later be legally liable for that person’s acts.

Presumptive disability

Assumption of total disability when an insured is considered totally disabled (blindness, loss of hearing, speech, or limbs). The insurance company may pay a lump sum in addition to monthly payments for a maximum benefit period.
***
A disability involving loss of sight, hearing, speech or any two limbs, which is presumed to be a permanent and total disability. In such cases, the insurer does not require the insured to submit to periodic medical examinations to prove continuing disability.
