Give Protection Against: In their simplest form, safety glasses are like standard ones, but with impact-resistant lenses. More sophisticated versions have ventilated side protection and non-fogging lenses. Safety goggles are the most robust, with safety lenses housed in a Flexible plastic frame. Gas welding goggles have a shaded lens. Ear protectors Foam earplugs with a connecting cord for easy removal are relatively cheap and give protection against noise levels above 80 decibels. More expensive - and more effective - are ear capsules or muffs, usually mounted on an adjustable headband, with interchangeable ear pads.
START PLANTING a hanging basket in mid- to late spring in warm areas, but wait until early summer in cold regions. Planting can be earlier if a greenhouse or conservatory is available to give the plants protection during cold nights in spring, when frost is forecast. They need a reasonably sunny position.
Instruments for Personnel Protection.—In order to provide maximum protection to personnel from the hazards of excessive nuclear radiation, three types of monitoring procedures are used in regions where exposure is likely; these include area monitoring, survey monitoring, and personnel monitoring. |
