  2. Safety integrity level - Wikipedia

    en.wikipedia.org/wiki/Safety_integrity_level

    The tolerable level of these risks is specified as a safety requirement in the form of a target 'probability of a dangerous failure' in a given period of time, stated as a discrete SIL. Certification schemes, such as the CASS Scheme (Conformity Assessment of Safety-related Systems) are used to establish whether a device meets a particular SIL. [4]

  3. Risk and Safety Statements - Wikipedia

    en.wikipedia.org/wiki/Risk_and_Safety_Statements

    Risk and Safety Statements, also known as R/S statements, R/S numbers, R/S phrases, and R/S sentences, is a system of hazard codes and phrases for labeling dangerous chemicals and compounds. The R/S statement of a compound consists of a risk part (R) and a safety part (S), each followed by a combination of numbers. Each number corresponds to a ...

  4. Risk assessment - Wikipedia

    en.wikipedia.org/wiki/Risk_assessment

    Risk assessment determines possible mishaps, their likelihood and consequences, and the tolerances for such events. [1] [2] The results of this process may be expressed in a quantitative or qualitative fashion. Risk assessment is an inherent part of a broader risk management strategy to help reduce any potential risk-related consequences. [1] [3]

  5. Risk register - Wikipedia

    en.wikipedia.org/wiki/Risk_register

    A Risk register plots the impact of a given risk over of its probability. The presented example deals with some issues which can arise on a usual Saturday-night party.. A risk register is a document used as a risk management tool and to fulfill regulatory compliance acting as a repository [1] for all risks identified and includes additional information [1] about each risk, e.g., nature of the ...

    en.wikipedia.org/wiki/ARP4761

    The Particular Risk Analysis (PRA) looks for external events which can create a hazard such as a birdstrike or engine turbine burst. The Zonal Safety Analysis (ZSA) looks at each compartment on the aircraft and looks for hazards that can affect every component in that compartment, such as loss of cooling air or a fluid line bursting.

  7. Process hazard analysis - Wikipedia

    en.wikipedia.org/wiki/Process_Hazard_Analysis

    A simple element of risk quantification is often introduced in the form of a risk matrix, as in preliminary hazard analysis (PreHA). The selection of the methodology to be used depends on a number of factors, including the complexity of the process, the length of time a process has been in operation and if a PHA has been conducted on the ...

  8. Risk matrix - Wikipedia

    en.wikipedia.org/wiki/Risk_matrix

    Risk is the lack of certainty about the outcome of making a particular choice. Statistically, the level of downside risk can be calculated as the product of the probability that harm occurs (e.g., that an accident happens) multiplied by the severity of that harm (i.e., the average amount of harm or more conservatively the maximum credible amount of harm).

  9. Fire Safety Certificate - Wikipedia

    The results of the performed tests are also entered into the corresponding protocol which serves as the reason for making decision for issuing the certificate. Basing on the decision made, the applicant receives the Certificate of Conformity to Fire Safety or not. The list of the documents necessary for drawing up the Fire Safety Certificate: OGRN;
