Also called "brown lung disease" or "Monday fever". Reaction against cotton, linen, hemp products in textile/fabric industry. Four (4) types of human errors discussed in Human Factors Engineering. "Errors C.O.S.T. time and money" 1. Commission: doing something wrong 2. Omission: leaving something out 3. Sequence: doing something in the wrong order 4. Timing: doing something out of allotted time, too fast or too slow Does the employers have to post OSHA citations? Yes, for 3 days or until corrected. Audiogram Written record of hearing threshold at specified frequencies. Audiometer a device that can present tones of different frequencies, from low in pitch to high in pitch, at different volumes from soft to loud What dB at 3000 hz during an audiogram means the person can't hear the tone? 30 dB Factors that affect absorption of noise angle to noise source, frequency of noise, density, condition/cleanliness, type of mounting, shape of surface To improve noise absorption through engineering controls, what properties do you want? Good porosity, thickness, air gaps Emissivity Ratio of radiation emitted by a surface to the radiation emitted by a black body at the same temperature. A black body is 1.0 (highest), down to 0 (bright, reflective surfaces). Emissivity of bright metal surfaces Low - less than 0.1 (bright metal is a good reflector), meaning it is good for reducing radiant heat.
