Objectives
1.TSW review common accidents
that occur in the greenhouse.
2. TSW discuss chemical safety.
3.TSW discuss greenhouse rules.
4.TSW quiz over ppt. Information.
Common Injuries
The list of injuries that commonly occur at greenhouses
throughout the country is quite long, and should be no
surprise. Here is a partial list:
• Slips, trips and falls
• Injuries due to repetitive bending, stooping,
overreaching or the repeated use of hands, fingers
and wrists for long periods of time
• Back injuries from improper or heavy lifting
• Being struck by large pots or other objects
improperly stacked on shelves
• Cuts to fingers or hands
• Getting fingers, hands or other body parts caught in
potting machines, conveyor belts or other equipment
Chemical Safety
• Only the instructor will handle pesticides with the
exception of less toxic substances. Such as
insecticidal soap and round-up.
• Before going into the greenhouse students will take
the Worker Protection Standards workshop and
recieve their WPS certification.
• While in the greenhouse or garden area and you are
exposed to toxic chemicals tell the instructor
immediatly.
• The three most common ways that you can have
chemical exposure are:
• Oral- by ingesting chemicals
• Dermal- by getting chemicals on your skin
• Inhilation- by breathing in fumes
Greenhouse Rules
1. No horseplaying
a) Throwing things
b) Squirting each other with hose
2. No running
3. If injured tell instructor at once
4. If you see someone being unsafe tell the
instructor
5. No food or drinks in greenhouse
6. Do not change greenhouse settings
7. Keep walk-ways clear of clutter
8. Put things back where you got them from
Ag. Chemical Safety
What is the WPS?
Worker Protection Standard
 WPS is a law that sets the rules for proper
use and disposal of chemicals.
 WPS determines the clothing and
protective equipment needed for
employees of agriculture operations.

Types of Pesticides
Insecticides- Kills Insects
 Miticides – Kills Mites and Aphids
 Fungicides – Kills Fungal organisms
 Herbicides – Kills unwanted plants
 Rodenticides – Kills Rodents
 Nematocides – Kills Nematodes
 Molluscicides – Kills Mollusks (snails,
slugs)

Ways Chemicals Enter The Body
Oral Contact (by swallowing)
 Dermal Contact (by contacting skin)
 Inhalation (by breathing)

Types of Toxicity
Acute Toxicity – the measure of how
poisonous a chemical is after one
exposure.
 Chronic Toxicity – the measure of how
poisonous a chemical is after a period of
time or after repeated exposures.

What must be on the Label







Name and Address of
Manufacturer
Trade Name
Active Ingredients
Type of Pesticide
Form of Substance
(WP, D, E, ect…)
EPA Number
Storage & Disposal
What must be on the Label
Hazard Statement
 Directions for use
 Net contents
 WPS Regulations for
that product

What are the Signal Words
Caution – Slightly Toxic (1 oz – 1 pint)
LD.
 Warning – Moderately Toxic ( 1 tsp – 1
oz) LD.
 Danger – Highly Toxic ( a few drops – 1
tsp) LD. Will also have a skull and
Crossbones on the label.

Reentry time (Danger – Poison)

Chemicals carrying the word “Danger –
Poison” have a reentry time of 48 hours
after application. This information should
be posted for all workers or visitors to the
farm or greenhouse. Do not enter these
areas without proper PPE (Personal
Protective Equipment) during the time
posted.
Reentry Time (Warning)
Areas treated with these agents should
not be reentered for 24 hours after
application. The owner/operator is
required to post this information clearly.
 The Owner/Operator is responsible for any
damages that occur as a result of the
application.

Reentry Time (Caution)
People may reenter the area as soon as
the dust or spray mist has settled in the
area.
 Areas treated with chemicals that carry no
label can be reentered immediately.

What should you wear
When applying
chemicals you need to
wear appropriate PPE
(Personal Protective
Equipment).
 The PPE should match
the equipment that is
recommended on the
product label.

What should you wear
Respirator with the
proper filters. Paint
filters will not work
for Ag Chemicals.
 Eye Protection to
prevent chemical
splashing into your
eyes.

What should you wear
Chemical Suit made
of a material that
does not absorb
chemicals.
 Rubber Gloves and
Boots. The sleeve of
the suit should go
over the gloves and
boots.

What must the Employer provide
1. PPE
 2. Water, Paper Towels, and Soap at
worksite.
 3. Phone number for emergency help and
directions to the Hospital, Clinic, ect…
 Training to employees on Chemical Safety
and WPS.
 This must be provided in proper language.

Chemical First Aid
Read all Label instructions before use.
 If spilled on the skin wash with soap and
water to dilute the chemical. Call Doctor
have EPA registration number handy.
 Remove any contaminated clothing. Put
on clean clothes or wrap in blankets.
Cover any chemical burns with loose clean
cloth.

Chemical First Aid
For eye poisoning, hold the eye open and
flush for five minutes.
 For inhalation victims, carry them to fresh
air, loosen clothes, and apply CPR if
breathing has stopped.
 Always consult doctor as soon as signs of
poisoning appear.

How do I work Safely





Wear PPE
Have water and soap
available to clean
spills.
Read label carefully.
Use extra caution
with concentrated
chemicals.
Only mix enough to
do the job.
How do I work Safely
Protect against
inhalation and
splashes
 Consider the weather
conditions.
 Store and dispose of
chemicals properly.

The End
WPS Quiz Time!
WPS Qz.
 (On your own paper answer the
following.)
1. What is WPS, who does it protect, and
what does it protect them from?
2. Name 3 types of pesticides and tell what
it is used to kill.
3. What are the 3 main ways chemicals can
enter our bodies?
4. List the three “Signal Words” from
weakest to strongest strength.

To get your WPS certification I am
required to train you in pesticide safety.
Even though you will not be a pesticide
handler you will be around pesticides and
will need to know what to do if exposed.
