Reasonable care

In general, polycarbonate resins have fair chemical resistance to aqueous solutions of acids or bases, as well as to fats and oils. Chemical attack by amines or ammonium hydroxide occurs, however, and aUphatic and aromatic hydrocarbons promote crazing of stressed molded samples. Eor these reasons, care must be exercised in the choice of solvents for painting and coating operations. Eor sheet appHcations, polycarbonate is commonly coated with a sihcone—sihcate hardcoat which provides abrasion resistance as well as increased solvent resistance. Coated films are also available. 

Thiols iateract readily with many mbber-containing materials. For this reason, care should be taken ia the selection of gasket and hose materials. Teflon, Kel-F, Viton, or other suitable fluoroelastomers function as gasket materials. Viton is suitable for hoses. Carbon steel is useful for many thiols, although some thiols become very discolored when carbon steel is utilized. In these cases, the use of stainless steel is very desirable. Isolation from air and water also minimizes color formation. 2-Mercaptoethanol and 1,2-ethanedithiol should be stored ia stainless steel (61). 

Cellulose nitrate is inflammable and explosive when dry, but when soaked in water it is considered entirely safe if reasonable care is taken in handling. 

Metal and plastic packing can be dumped dry into the tower however, reasonable care must be exercised, and the drop should not be more than 10-15 ft, using a chute with a cloth sock (open) on the end to cushion the impact.

The Act also places a responsibility on the employees in that they must take reasonable care to avoid injury to themselves or to others by their work activities, and cooperate with their employer and others in meeting all statutory requirements. The Act also requires that employees do not interfere with or misuse anything designed to protect their health, safety or welfare. 

It should always be remembered of course, that the NMR spectrum reflects a compound s behaviour in solution. It is quite possible for a compound and a weak acid to crystallise out as a stoichiometric salt and yet in solution, for the compound to give the appearance of a free base. For this reason, care should be taken in attempting to use NMR as a guide to the extent of protonation. If the acid has other protons that can be integrated reliably, e.g., the alkene protons in fumaric or maleic acid, then there should be no problem but if this is not the case, e.g., oxalic acid, then we would council caution Do not be tempted to give an estimate of acid content based on chemical shift. With weak acids, protonation may not occur in a pro rata fashion though it is likely to in the case of strong acids. 

Strict Liability The responsible party is liable even though they have exercised reasonable care. 

L Lack of reasonable care Evidenced by a failure to conduct operations according to accepted standards applicable at the time that is, a breach of regulatory requirements, or possibly failure to take account of or apply (industry) guidelines... 

C Causation The lack of reasonable care must have caused or contributed to the injury if a label would not have been read by the patient in any event, an omission from it might not have caused injury...

The development of tolerance is a major drawback to the use of benzodiazepines in the long-term treatment of insomnia. Whereas tolerance to the hypnotic effects of benzodiazepines permits them to be used without excessive sedation when treating anxiety disorders, this is counterproductive when attempting to treat insomnia. Patients often find themselves requiring higher doses to obtain the same sedative-hypnotic effect initially accomplished by lower doses. For this reason, careful consideration must be given before benzodiazepines are used to treat chronic insomnia. 

In theory, the practitioner, as a professional person, is able to assess the risks and potential benefits to his patient, and to decide that the balance lies in favour of the use of a particular unauthorised product. A company receiving a request from that practitioner will therefore assume that the doctor will exercise reasonable care and skill in using the product in a way that avoids causing injury to his patients. However, the principle that supply is the doctor s sole responsibility does not provide companies with total protection against liability where a patient is injured by treatment with an unlicensed product.

In order to provide minimum standards, certain terms are implied by law into any contract for the supply of goods or services unless they are expressly excluded. The actual terms of the agreement may exceed the minimum standards implied. For example, it would be implied by statute that services supplied in the course of a business must be carried out with reasonable care and skill and within a reasonable time. These terms may be substituted by more specific terms of agreement between the parties or by a course of dealing. 

Reasonable care must be taken in handling salt cells and plates. Moisture-free samples should be used. Fingers should not come in contact with the optical surfaces. Care should be taken to prevent contamination with silicones, which are hard to remove and have strong absorption patterns.
