A PHA has traditionally taken the form of inventorying all the materials and equipment to be used and deciding what are the hazardous elements. Intuition, experience and judgement are applied to determine what can lead to accidents and whether the risk is acceptable or the hazard must be corrected by controls and/or contingency plans. However, a more thorough review can be achieved with the following PHA procedure. 

What are the hazards of therapy with ethosuximide With sodium valproate ... 

Analyze new lab procedures and student-designed lab procedures in advance to identify any hazardous aspects. Minimize and/or eliminate these components before proceeding. Ask yourself these questions o What are the hazards ... 

What are the hazards For example, health hazards, flammability, reactivity, and physical hazards. 

Alcohols are considered to be toxic to the human body—with ethanol, the alcohol in alcoholic beverages, being the least toxic one. What are the hazards of ingesting (a) methanol and (b) ethanol ... 

What are the hazards in a lab Well, perhaps many. Academic labs for introductory classes likely have only limited numbers of chemicals and equipment, placed there for a particular lab. Bunsen burners aren t hazards until the gas stopcock is opened (assuming that it was closed properly by the last user ) and/or matches or strikers set the gas on fire. Electrical outlets are usually abundant, but no more hazardous than home outlets (except when near ubiquitous sinks). Most hazards in introductory labs are readily identified. Introductory organic labs are not much more hazardous, although the likelihood of encountering flammable solvents is much higher. So, your first few years of college chemistry classes likely do not provide the opportunity to have you conduct a scene survey since the labs you enter are not filled with unexpected hazards. It s easy to get complacent about walking into labs.

PROBLEM 16.54 There are many reagents that have been developed to oxidize alcohols to ketones or aldehydes. The chromium reagents work very well, but other procedures are preferred. Why do you suppose that other reagents are favored What are the hazards of using Cr(VI) ... 

Or we could further define risk as the triplet event scenario, probability of occurrence, and consequence. Event scenario is a description of the event under study. In safety parlance, what are the hazards Probability of occurrence is our quantification of the likelihood that the event will occur. Consequence is defined as the severity of the event. 

What are the hazards of the procedures What hazards are associated with the materials to be used Identify these before the experiment is begun. 

The problem of compliance thus recasts the problem of regulation (What are the hazards How great is the risk What shall we do ) into a question of time Will operators have enough time to abate conditions before they produce disaster ... 

Some of the major considerations to address in defining a commercial process are (1) How available is starting material (2) What is the cost of the starting material (3) What are the hazards or safety concerns The safety concerns to consider must be from the perspective of the chemical operator who is dealing with the chemicals, the equipment, and the environment.
