Prevent - meaning

To ensure that the safety program is working, most companies have a safety policy follow-through. This includes monthly safety meetings, performance reviews, and safety audits. The monthly safety meetings include a discussion of any accidents (and resolution of prevention means), training on specific issues, inspection of facilities, and delegation of work. Performance reviews within the company for all employees must have a visible safety performance component. [Pg.4]

In light of uncertainty about mechanisms and human dose-response, the assumption of low-dose linearity continues to be a reasonable one. The large and growing burden of cancer in the United States (now at 500,000 deaths per year) vividly demonstrates the need for prevention. Prevention means not only addressing those cancer risks already established as "major" contributors to the disease burden (such as smoking). . . but also reducing current involuntary exposures to identified industrial carcinogens. [Pg.79]

However, as mankind has exhausted the most accessible hydrocarbon supplies, more severe conditions (e.g., higher pressures, lower temperatures, and higher acid gas contents) caused thermodynamic prevention means to be less acceptable economically. The following two case studies illustrate the fact that thermodynamic inhibition is becoming very expensive. [Pg.656]

Corrosion and its control mean the corrosion process and the measures taken to control or keep in check the corrosion process. Sometimes it is also referred to as corrosion, prevention and protection. Although the terms prevention and protection appear to be synonymous, prevention means measures taken to control corrosion to a limited extent while protection means extensive or more comprehensive measures taken to control the corrosion process. In more general terms preventive measures are knowledge-based while protection involves both known and unknown factors, such as natural disasters. [Pg.4]

AV hen m exjfiansion nozzle is situated, or arranged to be situated, at the muzzle of the barrel, the nozzle may be constructed and arranged to constitute the vacuum-prevention means referred to in 75 the preceding paragraph. [Pg.86]

Means for preventing, or tending to prevent, the formation of a partial vacuum at the muzzle of the barrel is provided within the exi)ansipn chamber 16 in the casing HO 14. This vacuum-prevention means is constituted by an expansion nozzle 62 formed or provided on the muzzle 20, for which purpo.se the latter is serew-threaded externally, and the. stem of the 116 nozzle is screw-threaded internally. Preferably the internal face 64 of the nozzle has the sha]>e shown in Figure 6, which shows a maximum diameter B, a minimum diameter [Pg.89]

A variety of liquids have been treated with reverse osmosis and ultrafiltration membranes ranging from seawater, to wastewater, to milk and yeast suspensions. Each liquid varies in composition and in the type and fraction of the solute(s) to be retained by the membrane. Complicating factors include the presence of substances such as oil in seawater and wastewater [12-15]. The presence of the oil normally necessitates an additional pretreatment step further complicating the fouling process. The presence of humic acids in surface water and wastewater also needs special attention [16,17]. The fouling phenomena, the preventive means (i.e., pretreatment), and the frequency and type of membrane cleaning cycle are all dependent on the type of liquid being treated. [Pg.326]

Monoterpenic compounds have been applied as a preventive means against neo-plastic changes. The first report appeared in 1971 and was prepared by Homburger et al. [108] who applied d-limonene as a coadministered component together with the carcinogen benzo[rst]pentaphene, and thus obtained a reduction of the tumour growth. [Pg.386]

Finally, the SBP of Objective 10.4 are defined as The integrity of software and information against malicious and mobile code is protected by I awareness means - II code configuration means - III detection means - IV execution prevention means - V recovery means. [Pg.1882]

Because there are a mnnber of different areas to consider, preventability cannot be defined in a single sentence. First, everyone in the organization must understand that preventable does not necessarily imply blame or fault. In a nutshell, preventable means accountable. [Pg.726]

The term prevention can be used with several meanings. In line with ISO 13702 (1999), prevention means a reduction of the likelihood of a... [Pg.531]

Also as feedback, the students were exposed to some related industrial standards that address reduction of risk through safety barriers. For example, with respect to the concepts of risk prevention, control and mitigation, 180 13702 (1991), a standard for the oil gas industry) states that prevention means reduction of the likelihood of a hazardous event, control means limiting the extent and/or duration of a hazardous event to prevent escalation, while mitigation means reduction of the effects of a hazardous event. Hence, a barrier function is a one planned to prevent, control, or mitigate undesired events or accidents (Sklet 2006). [Pg.1992]

Core melting during handling shall be practically eliminated for instance thanks to appropriate prevention means and handling error detection system. [Pg.479]
