Potential injury

To be effective, the creation of a task or modification of a task through the introduction of new processes or equipment should automatically require you to develop a new or revised JHA. Jobs with many steps are usually good candidates. As stated before, you should assign each job selected a priority based on the accident potential and the severity of associated potential injuries. 

After the hazard assessment has been conducted and the data has been collected, it should be organized in a logical outline that will estimate the potential for employee injury The organized data will help to decide the type of hazard(s) involved, the level of risk, and the seriousness of potential injury The appropriate levels of PPE are then selected based on the hazard determination and the availability of PPE. The user should be properly fitted for the specified PPE, and the employer should make sure that it is comfortable to wear. Hazard reassessments should be conducted as necessary based on the introduction of new or revised processes, equipment, and accident experience, to ensure the continued suitability of selection of the proper PPE.

Good housekeeping can play a major part in maintaining a safe and environmentally sound place of work. Tripping over material not tidied away causes many accidents. Another source of potential injury is in the lack of secure storage of cleaning equipment, tools, etc. 

After phosphating, thorough rinsing with water is necessary in order to remove soluble salts which would otherwise tend to promote blistering under a paint him. Care should also be taken to ensure that the water supply itself is sufficiently free from harmful salts. Experience has shown that a water supply is potentially injurious if it exceeds any one of the three following limits ... 

The natural endogenous physiological antioxidant systems for controUing the potentially injurious elFects of environmentally exacerbated oxidative stress, may be modulated by a number of various nutritional and pharmacological supplementary interventions. 

The last measure to be taken, after other methods fail, is venting. However, venting may cause pollution of the environment and/or potential injury to operating personnel or the public. 

Like all of us, cells cannot survive without an external environment that operates successfully. The external environment brings oxygen and the nutrients needed to satisfy the cell s metabolic requirements. (Of course, they also bring foreign and potentially injurious chemicals to the cell.) These extracellular environments also allow for cells to maintain appropriate levels of fluids and electrolytes, and serve to remove cellular products that need to be excreted from the body. It is not hard to imagine how toxicant impairments of extracellular environments can be injurious. 

Recreating the potentially injurious conditions with an animal permits detailed examination of specific target tissues as well as observation on other systems and portions of the body. Unfortunately, large numbers of animals must be treated and maintained to obtain statistically significant results, and direct translation to the human condition is, at best, uncertain. 

The demonstration that PMNs formed O2- in the respiratory burst necessitated the consideration of all the species which result when dioxygen is reduced one electron at a time (Fig. 1). Superoxide, the result of the reduction of dioxygen by one electron, appears to act mainly as a mild reductant in aqueous solutions. But when it coexists with H2O2, its spontaneous dismutation product, O can initiate a number of potentially injurious events [reviewed by Fridovich The primary means by which cells deal with superoxide anions appears to be through the catalysis of their dismutation by a family of metalloenzymes collectively designated superoxide dismutases.

In order to ensure accuracy of vector delivery to the heart and to prevent any potential injury to the animal from any movements during vector administration, neonates are anesthetized by induced hypothermia in which the animals are wrapped in cellophane and floated in an ice water bath until their activity slows. The neonate will be removed from ice and placed on a pad under a microscope and fight, and rubbed down with a sterile alcohol pad. Up to 25 ul of vector can be directly injected into the heart through the chest cavity using a 33-gauge needle on a Hamilton syringe. 

A cell culture laboratory, in which activities are restricted to manipulation of established or pathogen-free derived cell lines, is a relatively safe workplace. Major risks are related to potential injuries resulting from liquid nitrogen manipulation or glassware accidents. 

Injury may be permanent, however, if a topical anesthetic is applied copiously to a compromised cornea. Anesthetics should never be dispensed to patients for use at home, and if other practitioners have dispensed anesthetics to patients for use on an as needed basis, these patients should be coimseled concerning this potentially injurious use of topical anesthesia. 

Similar to latanoprost and travoprost, bimatoprost has been reported to cause changes to pigmented tissues. These reports include pigmentation of the iris and periorbital tissue (eyelid). These changes may be permanent. The long-term effects on the melanocytes and the consequences of potential injury to the melanocytes and/or deposition of pigment granules to other areas of the eye are imknown. 

A short-term exposure limit ceiling of 25 ppm for acetaldehyde was recommended to prevent excessive eye irritation, lacrimation, and potential injury to the respiratory tract. 

Confusion often occurs with the use of the terms exposure , concentration , and dose . Dose is the amount of contaminant that is deposited or absorbed in the body of an exposed individual over a specific duration. Dose occurs as a result of exposure. Concentration is that level of contaminant present in the air potentially available to be inhaled. The atmospheric concentration of a chemical by itself does not define the total dose of a chemical delivered or the specific sites of potential injury. For a substance present in inhaled air to be toxic, a significant dose must first be removed from the inhaled air and be deposited on sensitive tissue. Knowledge of the dose to initial target sites provides a critical link between exposure and the subsequent biological response. Understanding the disposition of inhaled xenobiotics is complex and, due to space limitations, cannot be described in detail here. However, certain basic concepts need to be presented to provide information on the various factors related to exposure, dose, and response that are fundamental to understanding the potential human risk from inhaled chemical agents. 

Potential injuries include cuts from broken test tubes, bums from contacting hot water or hot plate, chemical bums from drain opener, etc. These are treatable on site.
