Write a review all lecture materials, specially the topics I mention every "Last Session Review". Pay extra attention on the following:
Intro to IH
- Elements of industrial hygiene
- People as early contributors to industrial hygiene
- Roles of an industrial hygienist
- Types of health hazards and specific examples
- Categories of control strategies
- Tools used in walk-through surveys (MSDS, process flow chart, plant layout)
- Use of IH instruments shown during 1st lab
Toxicology
- Concepts and definitions (dose-response relationship, threshold dose, LD50, acute vs chronic, nothreshold, safety factor, determinant)
- Factors affecting toxicity
- Routes of exposure/ entry for toxins
- Mechanisms for the distribution of toxin
- Mechanisms of neurotoxins
- Biotransformation
- Excretion of toxin
- Use of animal testing
- Theories in cancer causation (one-hit, initiation, promotion, no-threshold)
- Classes of toxins (irritants, sensitizers, etc.)
Occupational standards
- Types of exposure limits
- Calculation of TWA exposure
- Action level (definition, value for noise, etc.)
- Mixture rule (computations)
- Skin notation (definition)
- IDLH
- Important OSHA standards for an IH Program
- Composition of HAZMAT Team
- Confined space (definition, etc.)
Airborne hazards
- Protective mechanisms of the respiratory tract
- Aerodynamic diameter (definition)
- Different forms of particulates (dust, mists, fumes)
- Use of size-selective sampling
- Size fractions of particulates (inhalable, etc.)
- Occupational diseases caused by specific airborne hazards (silicosis, etc.)
- Calculation of PEL for different types of silica
- Simple vs chemical asphyxiant.

Identify each type of electromagnetic radiation.
: One type of electromagnetic radiation has a frequency of 1019 kHz, another type has a wavelength of 2.12 10^-10 m, and another type of electromagnetic radiation has photons with energy equal to 4.08 10^-22 J/photon

Collection of subsets of r are bases
: Determine which of the following collection of subsets of R are bases: solve each one individually. a) C1 = {(n,n+2) ⊆ R | n∈Z} b) C2 = {[a,b] ⊆ R | a

Determine the condition for constructive interference
: Bragg's Law applies to a very particular diffraction geometry. Determine the condition for constructive interference for the following, more general, geometric configuration. The incident beam approaches a row of point scatters at an angle x. the ..

Find the standard equation of a parabola
: Find the standard equation of a parabola with vertex at (5,1) passing through the point (10,-4). Remember to write your answers as exact numbers (fractions), rather than a decimal approximation.

Explain steady-state laser oscillation
: Repeat the calculation for the 3d^10 delta p 2^P_3/2 ---> 3d^9(delta)s^2 2^D_5/2 transition at 510 nm in the copper-vapour laser, given that the Einstein A coefficient is 2 x 10^6 s^-1 and the fluorescence lifetime of the lower laser level is appr..

How many staff does the company need to assign to the task
: If the company needs the task performed once per day over a 260-day working year and the maximum occupational dose limit is 20 mSv per year, how many staff does the company need to assign to the task?
