Wow! It’s going to be
dangerously cold over the next couple of days. Take the extra care to provide
for your pets, livestock, equipment and especially yourself during this week’s
forecasted a cold snap. I have attached links to a few helpful facts sheets or
links that may provide some useful information and helpful tips. There
are sections for Pets and Livestock, Equipment and Personal Care. If you
need additional assistance please let me know. Please remember to try to
check on your neighbors or others that you know may have difficulty in dealing
with these severe weather events.
Animal Emergency
Preparedness
When record cold, with
ice and snow hit, animal owners should be aware and ready to protect their pets
and livestock and do the proper things to help them through this unusual cold
spell. Following are a number of concerns and recommendations:
·
Hypothermia
and dehydration are the two most probable life-threatening conditions for
animals in cold weather.
- Many animals, especially indoor/outdoor pets, probably
do not have an adequate winter coat for protection in these very low
temperatures.
·
Wet
conditions and wind-chill add greatly to the cold-stress for animals (and
people).
·
Pets
should be brought inside or into protected covered areas, provided with plenty
of bedding and food and drinking water.
·
Livestock
should be provided with wind-break (natural or man made) and roof shelter, and
monitored for signs of discomfort (extensive shivering, weakness, lethargy,
etc.)
·
It
is very important that livestock be provided extra hay/forage/feed as up to
double the energy/calories for normal body heat maintenance may are required in
extreme cold.
·
It
is critical that animals have access to drinking water. Usual water
sources may freeze solid in low temperatures and dehydration becomes a
life-threatening factor. Many of our animals, especially the young, may
not know how or be unable to break several inches of ice to reach water.
In general, animals tend to drink less in extreme cold, risking
dehydration. Research with horses shows horses drink more water if it is
warmed during winter weather.
·
Adding
a warm sloppy bran mash, sloppy moistened beet pulp or soaking pelleted feed in
warm water is a good way to add water to your horses’ diet and provide some
“comfort food” in the cold weather.
·
Special
attention should be paid to very young and old animals. They may be less
able to tolerate temperature extremes and have weaker immune systems.
Make sure that young animals are capable of nursing and check teats for
frostbite or skin irritations that may limit suckling.
Fact sheets from places that deal with these
severe temps more often than we do.
What should I know about personal protective equipment (PPE) for working in
the cold?
Clothing
Protective clothing is needed for work at or below 4°C.
Clothing should be selected to suit the temperature, weather conditions (e.g.,
wind speed, rain), the level and duration of activity, and job design. These
factors are important to consider so that you can regulate the amount of heat
and perspiration you generate while working. If the work pace is too fast or if
the type and amount of clothing are not properly selected, excessive sweating
may occur. The clothing next to body will become wet and the insulation value
of the clothing will decrease dramatically. This increases the risk for cold
injuries.
·
Clothing should be worn in
multiple layers which provide better protection than a single thick garment.
The air between layers of clothing provides better insulation than the clothing
itself. Having several layers also gives you the option to open or remove a
layer before you get too warm and start sweating or to add a layer when you
take a break. It also allows you to accommodate changing temperatures and
weather conditions. Successive outer layers should be larger than the inner
layer, otherwise the outermost layer will compress the inner layers and will
decrease the insulation properties of the clothing.
·
The inner layer should
provide insulation and be able to "wick" moisture away from the skin
to help keep it dry. Thermal underwear made from polyesters or polypropylene is
suitable for this purpose. "Fishnet" underwear made from
polypropylene wicks perspiration away from the skin and is significantly
thicker than regular underwear. It also keeps the second layer away from the
skin. The open mesh pattern enables the moisture to evaporate and be captured
on the next layer away from the skin. The second layer covers the
"holes" in the fishnet underwear which contributes to the insulation
properties of the clothing.
·
The additional layers of
clothing should provide adequate insulation for the weather conditions under
which the work being done. They should also be easy to open or remove before
you get too warm to prevent excessive sweating during strenuous activity. Outer
jackets should have the means for closing off and opening the waist, neck and
wrists to help control how much heat is retained or given off. Some jackets
have netted pockets and vents around the trunk and under the arm pits (with
zippers or Velcro fasteners) for added ventilation possibilities.
·
For work in wet conditions,
the outer layer of clothing should be waterproof. If the work area cannot be
shielded against wind, an easily removable windbreak garment should be used.
Under extremely cold conditions, heated protective clothing should be made
available if the work cannot be done on a warmer day.
·
Almost 50 percent of body
heat is lost through the head. A wool knit cap or a liner under a hard hat can
reduce excessive heat loss.
·
Clothing should be kept
clean since dirt fills air cells in fibres of clothing and destroys its
insulating ability.
·
Clothing must be dry.
Moisture should be kept off clothes by removing snow prior to entering heated
shelters. While the worker is resting in a heated area, perspiration should be
allowed to escape by opening the neck, waist, sleeves and ankle fasteners or by
removing outerwear. If the rest area is warm enough it is preferable to take
off the outer layer(s) so that the perspiration can evaporate from the
clothing.
·
If fine manual dexterity is
not required, gloves should be used below 4°C for light work and below -7°C for
moderate work. For work below -17°C, mittens should be used.
·
Cotton is not recommended.
It tends to get damp or wet quickly, and loses its insulating properties. Wool
and synthetic fibres, on the other hand, do retain heat when wet.
Footwear
Felt-lined, rubber bottomed, leather-topped boots with
removable felt insoles are best suited for heavy work in cold since leather is
porous, allowing the boots to "breathe" and let perspiration
evaporate. Leather boots can be "waterproofed" with some products
that do not block the pores in the leather. However, if work involves standing
in water or slush (e.g., fire fighting, farming), the waterproof boots must be
worn. While these protect the feet from getting wet from cold water in the work
environment, they also prevent the perspiration to escape. The insulating
materials and socks will become wet more quickly than when wearing leather
boots and increase the risk for frostbite.
Foot Comfort and Safety at Work has some
general information how to select footwear. (Also, when trying on boots before
purchase, wear the same type of sock that you would wear at work to ensure a
proper fit.)
Socks
You may prefer to wear one pair of thick, bulky socks or
two pairs - one inner sock of silk, nylon, or thin wool and a slightly larger,
thick outer sock. Liner socks made from polypropylene will help keep feet dry
and warmer by wicking sweat away from the skin. However, as the outer sock
becomes damper, its insulation properties decrease. If work conditions permit,
have extra socks available so you can dry your feet and change socks during the
day. If two pairs of socks are worn, the outer sock should be a larger size so
that the inner sock is not compressed.
Always wear the right thickness of socks for your boots.
If they are too thick, the boots will be "tight," and the socks will
lose much of their insulating properties when they are compressed inside the
boot. The foot would also be "squeezed" which would slow the blood
flow to the feet and increase the risk for cold injuries. If the socks are too
thin, the boots will fit loosely and may lead to blisters.
Face and Eye Protection
In extremely cold conditions, where face protection is
used, eye protection must be separated from the nose and mouth to prevent
exhaled moisture from fogging and frosting eye shields or glasses. Select
protective eye wear that is appropriate for the work you are doing, and for
protection against ultraviolet light from the sun, glare from the snow, blowing
snow/ice crystals, and high winds at cold temperatures.
What are some additional prevention tips?
·
To prevent excessive
sweating while working, remove clothing in the following order:
o mittens or gloves (unless you need protection from snow or ice),
o headgear and scarf.
·
Then open the jacket at the
waist and wrists, and
·
Remove layers of clothing.
As you cool down, follow the reverse order of the above
steps.
Prevent contact of bare skin with cold surfaces
(especially metallic) below -7°C as well as avoiding skin contact when handling
evaporative liquids (gasoline, alcohol, cleaning fluids) below 4°C. Sitting or
standing still for prolonged periods should also be avoided.
Balanced meals and adequate liquid intake are essential
to maintain body heat and prevent dehydration. Eat properly and frequently.
Working in the cold requires more energy than in warm weather because the body
is working to keep the body warm. It requires more effort to work when wearing
bulky clothing and winter boots especially when walking through snow.
Drink fluids often especially when doing strenuous work.
For warming purposes, hot non-alcoholic beverages or soup are suggested.
Caffeinated drinks such as coffee should be limited because it increases urine
production and contributes to dehydration. Caffeine also increases the blood
flow at the skin surface which can increase the loss of body heat.
Alcohol should not be consumed as it causes expansion of
blood vessels in the skin (cutaneous vasodilation) and impairs the body's
ability to regulate temperature (it affects shivering that can increase your
body temperature) . These effects cause the body to lose heat and thus increase
the risk of hypothermia.
In refrigerated rooms, the air speed should not exceed 1
meter per second. If workers are simultaneously exposed to vibration and/or
toxic substances, reduced limits for cold exposure may be necessary.
Farm
Machinery:
It
is a good idea to make a checklist of the seven or eight items to evaluate on
each piece of machinery. Use the owner’s manual as a starting point, but a
personalized list will be helpful to look back on year after year.
The
following list includes the basic winterizing steps to get all of your
machinery ready for its next use. Try to check off these projects as soon after
harvest as possible to protect equipment before winter hits.
•
Clean dust, dirt and grime off of equipment.
•
Conduct a visual inspection to see what might need repair. Make note of things
like burned-out headlights and cracks in the windshield glass.
•
Change the oil and filters.
•
Check the cooling system.
•
Check the battery.
•
Change the air filters.
•
Properly lubricate or grease equipment.
•
Top off the fuel and add a fuel stabilizer.
Fall
is a great time to tune up tractors that will continue to be used throughout
the winter. Lubricants and greases become thicker in colder temperatures,
making it more difficult to operate equipment. A lighter fluid such as Cenex
Superlube TMS® 10W-30 is a good engine oil for cold weather and winter work.
Farm
machinery requires maintenance both on and off the field to keep it running
smoothly year after year. Caring for equipment is one way to ensure efficient
fieldwork and less downtime.
