Material Safety Data Sheet (MSDS) – A safe read
In Canada, every material that is controlled by the Workplace Hazardous Materials Information System (WHMIS) must be labelled and have an accompanying Material Safety Data Sheet (MSDS) that is specific to the product or material. Both the product name and supplier on the MSDS must match the material in use. An MSDS is a document prepared by the chemical manufacturer or supplier that contains information on the potential health, fire and reactivity hazards of the product. The MSDS also describes how to use, store and handle the product safely and what to do in an emergency. It tells how to recognize symptoms of exposure and what first aid and other procedures might be necessary.
MSDSs come from many sources and may not all look the same, but they must include these 9 categories of information
1. Product information – for example, product identifier (name), manufacturer and supplier’s names, addresses and emergency telephone numbers
2. Hazardous ingredients
3. Physical data – for example, physical state, odour and boiling point
4. Fire or explosion hazard data
5. Reactivity data – for example, conditions under which the product is chemically unstable and the names of other substances the product is incompatible with
6. Toxicological properties – health effects
7. Preventive measures – for example, personal protective equipment and engineering controls
8. First aid measures
9. Preparation information
The law doesn’t expect you to know everything about all chemicals, but you must get to know the hazards, control measures and emergency procedures for each chemical product you work with. Familiarize yourself with this information from the MSDS before you start to use the product. In addition, your employer should supplement the MSDS information with sitespecific information and training regarding first aid measures, hazard controls (for example, required ventilation, gloves) and what to do in case of an emergency (for example, spill or leak).
The Controlled Products Regulations specify that an MSDS for a controlled product must be no more than 3 years old. It’s up to the supplier to update the product label and MSDS. Employers must ensure that every controlled product entering the workplace is accompanied by a current MSDS. The company’s MSDS collection must be widely accessible to workers who may be exposed to the controlled products, and to the health and safety committee or representative. They can be stored in a binder or digitally on a computer network, as long as everyone in the workplace has easy access to them at all times.
The Canadian Centre for Occupational Health and Safety (CCOHS) – eNewsletter, December 2007
1. What 2 things must an employer do with materials controlled by the Workplace Hazardous Materials Information System (WHMIS)?
2. Why do you think reactivity data information must be listed on each Material Safety Data Sheet (MSDS)?
3. How often must each MSDS be updated for a controlled product?
4. Why is it important for all employees to have access to MSDS information?

Answer
 Materials controlled by WHMIS must be labelled and have an accompanying MSDS that is specific to the product or material.
 The reactivity data information is included because you need to know conditions under which the,product is chemically unstable and the names of other substances the product is incompatible with.
 MSDS must be updated at least every three years.
 Employees need access to the MSDS information because they need to know about the hazards of the chemicals they may be exposed to, as well as the safe usage, storage and handling of the product. Also, they must be able to recognize the symptoms of exposure and the firstaid response.
Document use
Finding, understanding or entering information such as text, symbols and numbers in documents such as tables or forms.
WHMIS symbols
Look at the following health and safety poster and answer the questions on the following page.

2. What harm can corrosive materials have on your skin?
3. Class D1 deals with poisonous and infectious materials. How soon after contact with these materials would you see a reaction?
4. If you worked with materials labelled with the following symbol, what precautions would you take?

Answer
Question 1. A line points to the WHMIS logo in the bottom left corner. WHMIS stands for Workplace Hazardous Materials Information System
Question 2. A line points to an image with liquid spilling out of a container and causing corrosion to a solid object and a hand. This image represents Class E corrosive material. Corrosive materials can burn skin.
Question 3. A line points to an image of a skull and crossbones that represents Class D1 Poisonous and infectious material. Material causing immediate and serious effects. Contact with poisonous and infectious materials can produce an immediate and serious reaction
Question 4. A line points to an image of flames above a line that represents Class B Flammable and Combustible Material. Materials labelled with the flammable or combustible symbol should be kept away from open flame or high heat.

When you change to equivalent fractions, you must begin by making the denominators (the bottom part of the fractions) the same. Then, whatever you do to one denominator to make it the same as the other denominator, you must also do to the numerator (top part of the fraction) of the same fraction.
In the example below, multiply the denominator of 8 by 2 to get 16 (the same as the other denominator as the other fraction), then multiply the numerator by that same number, in this case 2. This creates an equivalent fraction with a denominator of 16.
5/8 × 2/2 = 10/16
To find the decimal, divide the denominator by the numerator.
To change a decimal to a percentage, you must multiply the decimal by 100.0.625 x 100 = 62.5%

How to reach the answers
When you are adding and subtracting fractions it is necessary to get a common denominator (the same number in each denominator). You get a common denominator by multiplying in a similar manner as in section 2.a. 1/2 × (2/2) = 2/4 + 3/4 = 11/4
b. 17/32  5/16 × (2/2) = 17/32  10/32 = 7/32
When a fraction has whole numbers in addition to fractions, you can simply add or subtract the whole numbers in the final step of the problem. If you get a final answer that is greater than 1, then you will need to express it as a mixed fraction and add the whole number to the other whole numbers in the equation.
c. 215/16 + 15/8 = 215/16 + 15/8(2/2) = 215/16 + 110/16 = 325/16 = 49/16
When you are subtracting fractions, sometimes it is necessary to change a mixed fraction into an improper fraction. (See d below)
d. 11/4  9/16 = 11/4 × (4/4)  9/16 = 14/16  9/16 = 20/16  9/16 = 11/16
e. 33/16  17/8 = 33/16  17/8 (2/2) = 33/16  114/16 = 219/16  114/16 = 15/16
f. 21/2 + 5/16 = 21/2 (8/8) + 5/16 = 28/16 + 5/16 = 213/16
When you are multiplying fractions you must multiply straight across the numerator and straight across the denominator of each fraction. It might be necessary to change the fraction into an improper fraction, multiply and then reduce. (See h below)
g. 3/4 × 1/2 = (3 × 1)/4 × 2 = 3/8
h. 21/2 = (2 × 2 + 1)/2 = 5/2 × 8 = 5/2 × 8/1 = 5 × 8/2 × 1 = 40/2 = 20
When you are dividing fractions you change the sign from division to multiplication and invert the fraction you are dividing by. Another way this is described is multiplying by the reciprocal.
i. 220 ÷ 3/4 = 220 × 4/3 = 220/1× 4/3 = (220 × 4)/3 × 1 = 880/3 = 2931/3
j. 11/16 ÷ 1/8 = 11/16 × 8/1 = 88/16 = 44/8 = 22/4 = 11/2 =51/2

Answer
How to reach the answers
When you are converting from one unit to another you must multiply the given quantity by an equivalent fraction that has the original units in the denominator and the desired units in the numerator. If the original units appear in the numerator and the denominator, then they will cancel each other out and leave only the desired unit.
Example: Convert 4 days into minutes.
4 days/1 x 24 hours/1 day x 60 min/1 hour = 4 x 24 x 60 min = 5 760
Notice that the units of 'days' will cancel (the unit is in the numerator and denominator) and the units of 'hours' will also cancel. This leaves the desired unit of minutes in the numerator. Multiply all of the numbers together to get 5 760 minutes.
a. 1 440 min/1 × 1 hour/60 min = 24 hours
b. 220 inches/1 × 1 foot/12 inches = 18.333 feet = 18 feet 4 inches
c. 2.5 hours/1 × 60 min/1 hour = 150 minutes
d. 90 inches/1 × 2.54 cm/1 inch = 228.6 cm
e. 1 fluid cup/1 × 8 ounces/1 fluid cup = 8 ounces
f. 120 mm/1 × 1 cm/10 mm = 12 cm
Word problems
5. Please answer the following questions about a firstyear apprentice’s rate of pay and earnings. The minimum wage rate for a firstyear apprentice is 180 percent of a province’s minimum wage, which is $8.50 an hour.
 What is the hourly wage for a firstyear apprentice?
 Using the hours listed in the following table, what was the firstyear apprentice’s pay for the week?
Schedule Monday 7.25 hours Tuesday 6.0 hours Wednesday 11.25 hours Thursday 10.5 hours Friday 5.0 hours  The overtime rate of pay per hour is “time and a half.” What would the firstyear apprentice be paid per hour when working overtime?

Answer
a. Since percentage is really just a fraction that has a denominator of 100, 180% is 180/100.
$8.50 x 180/100 = $15.30
b. Add up all the hours for the week.
7.25 + 6.0 + 11.25 + 10.5 + 5.0 = 40 hours
40 hours x $15.30 = $612.00
c. Time and a half would be 1.5 times your hourly wage.
1.5 x $15.30 = $22.95 per hour
6. You filled up the gas tank with 75L (litres) of fuel at $1.24/L (per litre). The attendant gives you a 4 percent discount. How much will you pay, in total, for the gas?

Answer
The total cost would be 75 litres x $1.24 per litre = $93.00. With a 4% discount deducted from the bill, the total is $93.00 – $3.72 = $89.28.
7. A vehicle travelled 33 000 km (kilometres) in 2 years.
 The oil is changed every 5 000 km. Each oil change uses 5 litres of oil. How many litres of oil were used in total?
 At the same usage rate, if a vehicle travels 33 000 km in 2 years, how many kilometres will the vehicle have travelled in 10 years?

Answer
a. If an oil change is done every 5 000 km, then there would have been 33 000/5 000= 6.6 oil changes in total.
Since we cannot have part of an oil change, then we would be in between our sixth and seventh oil change. There would have been 6 actual oil changes. If there are 5 litres of oil used per oil change, then there would have been 6 oil changes x 5 L per oil change = 30 L of oil in total.
b. 33 000/2 years = 16 500/year
16 500 x 10 years = 165 000 km

8. Refer to the following figure to answer the questions below.
 What is the perimeter of this rectangle?
 What is the area of this rectangle?

Answer
a. The perimeter of any object is the distance around the outside of that object. In this case,
perimeter P = 2 (l + w).
P = 2 (12 m + 18 m) = 60 m
b. The area is A = l x w = 12 m x 18 m = 216 m2
9. The radius of the circle below is 4 cm, as shown.
 What is the diameter of this circle?
 What is the circumference of this circle?
 What is the area of this circle?

Answer
a. The radius is half the length of the diameter. Since r = 4 cm, the diameter will be 2 x 4 cm = 8 cm.
b. The circumference of a circle is the distance around the outside (it is the perimeter of the circle).
Perimeter = Circumference = 2 ? r = 2(3.14)(4 cm) = 25.12 cm.
c. Area = ? r2 = ? (4 cm)2 = 50.24 cm2
A = 3.14 x (4) x (4)
A = 3.14 x 16
A = 50.24 cm2
Notice that area is twodimensional and therefore has square units (cm2).
10. What is the volume of this figure?

Answer
Volume = 48 in.3
How to reach the answer
Volume is the amount of space an object takes up.
V = l x w x h = 8 x 2 x 3 = 48 in.3
Notice that volume is a threedimensional measure and therefore has cubic units (in.3).
11. Consider this rightangled triangle to answer the questions that follow.
side a = 12 m and side b = 9 m
 How long is side c?
 Place an “S” on the diagram to show the smallest angle of the triangle.
 In degrees, what is the smallest angle in the triangle?

Answer
a. Use the Pythagorean Theorem ( a2 + b2 = c2) to solve for side c. Remember: side c is the hypotenuse which is always opposite the right angle.
12 m2 + 9 m2 = c2
144 m + 81 m = c2
225 m = c2
15 m = c
b.
How to reach the answer
The smallest angle of any triangle is opposite the smallest or shortest side in the triangle, and the largest angle is always opposite the longest side.
c. Using right angled trigonometry:
tan S = Opposite/Adjacent
tan S = 9/12
tan 1 = (9/12) = S
S = 36.87°
12. Consider another rightangled triangle.
side a = 9 cm and side c = 41 cm
 How long is side b?
 Place an “S” on the diagram to show the smallest angle of the triangle.

Answer
a) side b = 40 cm
How to reach the answer
9 cm2 + b2 = 41 cm2
b2 = 1681 cm  81 cm
b2 = 1600 cm
b = 40 cm

18. Consider the list of 9 lengths of pipe below to answer the questions that follow.
8 cm, 15 cm, 3 cm, 8 cm, 80 cm, 12 cm, 8 cm, 25 cm and 15 cm
 List the lengths of pipe in order from shortest to longest.
 What is the middle (median) length of pipe?
 What is the most common (mode) length of pipe?
 What is the average (mean) of all the lengths of pipe?
 How would the mean length of pipe be affected if the longest length were removed from the list of pipe lengths?

Answer
a. 3 cm, 8 cm, 8 cm, 8 cm, 12 cm, 15 cm, 15 cm, 25 cm, 80 cm
b. Median = 12 cm
The median is the middle number in any data set. To determine the median, place measurements in order from highest to lowest. Since there are 9 measurements in this data set, the middle number is the fifth measurement. In this list the 5th measure is 12 cm.
c. Mode = 8 cm
The most common (or mode) of the data is the number that occurs the most often. In this list the most common number is 8 cm so this is the mode.
d. Mean (average) = 19.33 cm
The mean or average of a data set is calculated by adding up all the numbers and dividing by the amount of numbers in the data set.
average = 8 cm + 15 cm + 3 cm + 8 cm + 80 cm + 12 cm + 8 cm + 25 cm + 15 cm / 9 = 19.33 cm
e. The mean would decrease.
If the longest length of pipe were removed the average length would decrease. This can be proven with the same calculation as in (d).
average = (8 cm + 15 cm + 3 cm + 8 cm + 12 cm + 8 cm + 25 cm + 15 cm)/8 = 11.75 cm
If you remove a number that is higher than the mean, the mean will decrease and if you remove a number that is below the mean, the mean will increase.

Date: January 27
My name is Pat King and I’m a prep cook in the hotel kitchen. Yesterday, I was working the early morning shift by myself. My job was to deepfry the potatoes to get them ready for the breakfast rush. It was just after 7:00 am and I was running a little late. I went to take the last batch out of the deep fryer and when I shook the wire basket, my hand slipped and landed in the hot oil. I started yelling and shaking my hand to get the oil off but then the oil hit the flames on one of the burners and started a fire. The heat sensor on the exhaust hood must not have been working, because the fire damper didn’t come on. The fire kept getting bigger and I couldn’t reach the fire extinguisher. I kept yelling for help. Finally, one of the cleaning staff came, grabbed the fire extinguisher and put out the fire. He also called 911. Luckily, the fire only damaged the stove top and the exhaust hood is all black. When my supervisor came in, I told her everything that happened. Then the emergency workers came and gave me first aid for a minor burn. I took the rest of the day off and I’m not scheduled again until next week.
