On the basis of these differences in species response it was concluded that phthalates do not pose a significant health hazard to humans. This view is home out by the EU Commission decision of July 25, 1990 which states that DEHP shall not be classified or labeled as a carcinogenic or an irritant substance (42). This has been reaffirmed in a comprehensive review (43) which concludes that "peroxisome proliferators constitute a discrete class of nongenotoxic rodent hepatocarcinogens and that the relevance of thek hepatocarcinogenic effects for human hazard assessment is considered to be negligible."... 

Skin irritation potential is assessed by patch tests. More serious than simple irritation is the potential of a product to cause sensiti2ation, ie, to cause a subject to become allergic to even very small amounts of the product. 

The effects of dmgs and adjuvants must be assessed, both in short-term administration and during chronic treatment. Local effects include changes in mucocihary clearance, cell damage, and irritation. Chronic erosion of the mucous membrane may lead to inflammation, hyperplasia, metaplasia, and deterioration of normal nasal function (76). 

None of the foregoing methods will tell the frequency or duration of exposure of any receptor to irritant or odorous gases when each such exposure may exceed the irritation or odor response threshold for only minutes or seconds. The only way that such an exposure can be measured instrumentally is by an essentially continuous monitoring instrument, the record from which will yield not only this kind of information but also all the information required to assess hourly, daUy, monthly, and annual phenomena. Continuous monitoring techniques may be used at a particular location or involve remote sensing techniques. 

Threshold Limit Value Ceiling (TLV-C) The concentration that RDA should not be e, cceded during any part of the working e. posure. If conventional industrial hygiene instantaneous monitoring is not feasible, then the TLV-C can be assessed by sampling over a 15-minute period except for those substances that may cause immediate irritation when exposures arc short. 

When the nurse is administering any of the miscellaneous drugs, the nurse monitors die patient for a reduction in the symptoms obtained in die preadministration assessment such as dysuria, urinary frequency, urgency, nocturia, and relief of any pain associated widi irritation of die lower genitourinary tract. 

The nurse assesses the patient s response to therapy. For example a decrease in pain or inflammation should occur. The nurse examines the outer ear and ear canal for any local redness or irritation that may indicate sensitivity to die drug. 

During the ongoing assessment the nurse observes for a therapeutic drug effect and reports any increase in symptoms and the presence of any redness, irritation, or pain in the eye. Patients admitted for treatment of acute glaucoma should be assessed every 2 hours for relief of pain. Pain in the eye may indicate increased IOP... 

The skin condition reflects the skin irritation elicited by a surfactant when applied. Skin surface appraisal is hence a means for assessing product mildness.
