Weatherworkingplan describes the control mechanismsneededtoensure incase of adverse
weather condition at C38 District, EXPO 2020 in Concourses and Arrivals Plazas at EXPO 2020
site and to detail the following:
• When work is to be abandoned
• Mitigation measures to protect workers from extreme conditions
• Return to work requirements
2 Responsibility
Project Director or Sr. Project Manager will take sole decision to abandon work on advice and
recommendation from Construction Manager and HSE Manager.
3 Communication
In Expo 2020 projects, every adverse weather forecast will be communicated by the Expo
Logistics Team to the concerned department in every project. For C38 District, EXPO 2020 in
ConcoursesandArrivalsPlazas,LogisticDepartmentwill be informedandwill communicatethe
same to every department of the project. Moreover, HSE Department will ensure day to day
followupwiththeNational Centre of Meteorology(NCM) andinformthesite teamregardingthe
weather conditions from time to time.
4 Weather Conditions
The below listedweatherconditionsare the conditionswhich are hazards for workand chances
of injuries and damages are increased on project site. These injuries or damages could be
eliminated or reduced with early planning.
 Hot Weather(over40O
C)
 Highwinds
 Sandstorms
 HeavyRain& Flood
 Hail
 Fog
In worst case scenario, the workers must be sent back to camp after such decision is taken
from the top site management.
When the weather condition improves, the following inspections must be done by competent
persons before deploying the workers back to site.
 All internal site access or egress routes/points, hoardings.
 All cranes.
 All electrical DB’s and cables must be checked by electrician to identify any damages.
 All loose materials on the edges must be removed or secured again.

4.1 Hot weather (over 40ºC)
New workers (acclimatization of hot weather)
 New comers must not be directly sent to external works as well as those works which
has limited air circulations, until their body get adjusted to temperatures above 40ºC.
Theymustbe exposedslowlyinitiallyforfew hoursin the firstcouple of days.Theymust
be inducted andadvisedtotake plentyof waterandbreaks asneededtokeeptheirbody
cool.
 These workerswill be grantedworkinginshiftstoabsorb acclimatization processof hot
weather working condition.
General Arrangements:
Workerswill be providedwith plentyof chilledwateratsite andthey will be encouragedto
use minimum 2 liters or more water daily.
Workerswill be suppliedwithOral Rehydration Solutions (ORS) orany electrolyte drinksas
approved by local health authority.
Workerwill be givenlemonandsaltwatertoreduce the riskof losingexcessivesalttoavoid
any heat related illness.
Site management will recommend one or more combination of drinks to workers.
Where ever possible, work under shade (temporary shading) will be encouraged and
necessary arrangements will be taken to ensure workers’ safety. During peak hours, work
at height, confined space and inside excavation will not be allowed.
Water Stations(withoverheadshade) willbe placed atthe site where watercoolersandor
chilledwaterinthermos(containers) are provided.Suchwaterstationswill be providedat
every work activity zone,to be monitoredand ensuredthat adequate amount of drinks is
available.
Foremanand Charge hands willensure‘WaterStations’are providedateveryworkareaand
ensure their workers are drinking enough water and are provided with ORS adequately.
BeginningApril,‘HeatStress’trainingwill commence andworkerswill be regularlytrained
in differentbatchesregardingthe same. The same topic will be discussedonevery‘Safety
StandDown’conductedonweeklybased(everyMonday) untilSeptember end(oruntil the
hot weatherlasts).External trainingwill alsobe conductedtwice duringthisspan forall the
workers. Such a way, all employees will acquire self-awareness regarding the subject
mentioned.

to ensure workersafety.
TWL, measuredinwattspersquare meter(W/m2),is the maximumrate at whichheatcan
be lost to the environment in the conditions. TWL is calculated from environmental
parametersassumingthatworkersare wellhydratedandacclimatizedtothe conditionsand
are self-paced.
TWL Station
Project weather stations which record the Thermal Working Limit (TWL) will be provided,
thisshall be calibratedperiodicallyby3rd
partytoensure the accuracyandconformityof the
readings. This will be submitted in the month of May or before the start of hot weather.
The TWL readings willbe monitoredandrecordedby the HSEDepartmentondailybasis and
will be communicated to the Project team and to the workers through WhatsApp group,
TBT, Daily Task briefing and flag system.

The arrangement for flag colour system and red alerts will be communicated and ensure
that is fully understood by the entire workforce through TBT, trainings and induction.
TWL can be determined through the following measurement, however a Thermal Work
Limit device which directly measures TWL will be available at site.:
 Dry Bulb Temperature (ambient air temperature) (in degrees °C)
 Wet BulbTemperature (determinedbythe humidity/evaporation) (In degrees °C)
 Globe Temperature (determined by the radiant heat) (In degrees °C)
 Wind speed in meters per second
The thermal environmentcanbe classified basedon TWL intothe followingworkingzones.
Notes:
a. Self-pacedwork – workers must be allowed to adjust their work rate according to
environment conditions. Paced work is when the work rate is not under the
worker’s control.
b. Unacclimated workersare definedasnew workersorthosewhohavebeenoffwork
for more than 14 days due to illness or on vacation leave (in a cool climate area)
c. Light Work – sitting or standing, light arm work.

Heat related illness
All employees on C38 District, EXPO 2020 in Concourses and Arrivals Plazas shall be
provided the basicinductiontrainingandtool box talksforHeat relatedillnessandcontrol
measures which will describe required first aid treatment.
Postersandregulartool box talkswill be carriedoutfrommonthof April toensurethat the
workersunderstandheatrelatedillnessandtheircontrol measures.Thiswill be carriedout
till end of September.
Following methods will be followed in the event of heat related illness:
Treatment:
 Restin a cool or shadyarea
 Drinkwateror otherfluids
 Take additional saltif advised.
 Use cool compressesonforehead,aroundthe neck
 Seekmedical attention
Sun Burn
Cause - Too much exposure to sun
Symptom - Red painful/blistery and peeling of skin
Treatment - If the skin blister seeks medical aid. Use skin lotions like “Calamine” and
arrange work in the shaded area.
Prevention - Work in the shade,cover skinwithclothing,applyskinlotionswitha sun
protection factor of at least 15spf.
Heat Cramps
Cause - Heavy sweating, drains a person’s salt in the body.
Symptom - Painful cramps in arms, legs, stomach which occur suddenly at work.
Treatment - Move to cool area, loosenclothinganddrinkcool saltedwater.If cramps are
severe seek medical aid.
Prevention - Reduce activity level/heat exposure, drink fluids regularly, Worker should

Fainting
Cause - Fluid loss and inadequate water intake.
Symptom - Sudden fainting after at least 2 hours of work, cool moist skin, weak pulse.
Treatment - GetMedical Attention, movetocool area,loose clothing,make the personlie
down, if person is conscious offer sips of cool water.
Prevention - Reduce activity level/heat exposure, drink fluids regularly, Workers should
check each other to help spot the symptoms that often precede heat stroke.
Heat Stroke
Cause - If a person’s body has used up all its water and salt reserve, it will stop
sweating. This can cause body temperature to rise. Heat stroke may develop
suddenly or may follow from heat exhaustion.
Symptom - High body temperature over 40C, the person is weak, confused or acting
strangely, fast pulse, head ache or dizziness could occur.
Treatment - First Aider/Nurse must call Ambulance. Remove excess clothing, spray the
personwithcool water, andoffersipsof cool waterif the person is conscious.
Prevention - Reduce activity level/heat exposure, drink fluids regularly, Workers should
check each other to help spot the symptoms that often precede heat stroke.
Heat Stress and Electrolytes
The bodyneedscontinuoussupplyof fluidsandelectrolytes,chemical ionswhichbalances
the body fluid in and around the cells.
The key electrolytes are Sodium Na+, Potassium K+, Chloride Cl- and Bicarbonate HC03-
Whena personis underheat stressacid concentrationincreasesandthe body’sbalance is
upset. To avoid this, ensure intake of more water.
4.2 High Winds
Strong or high winds will create potential hazardstothe constructionactivities.Expo 2020
site is at an open area; the site is vulnerable to face high winds.
In the event where the wind speed is above 38 Km/hr., all the lifting works and work at
height will be suspended, other external works must be ensured by the concerned
supervisors thatthatit is safe to continue.Otherwise the activities will be ceasedtill wind
normalizes to safe working condition. All the materials must be secured as they can be
blownawayby the wind,injuringsomeone ordamaging equipment. Appropriatematerials
will be made available on the project to facilitate in securing the property, materials and
equipment.

Crane Operations should be suspended for wind speed of 38 Km/hr. and more. However,
the operatorisself-authorizedto suspendtheoperationsifhe feelsthathe cannot maintain
full control of the load even before the wind speed reaches 38 km/hr. Strong winds may
swing suspended loads (crates, panels, etc.) out of balance and radius, making the
crane/lifting unstable.
Althoughthe stormmayhave passed,hazardsmaystill existbecause of unstable structures
or otherhazardousconditions.Therefore,asafetyandpropertydamageassessmentwillbe
conductedbythe Constructionteamandpassedtothe HSE teamon site,for plannedclean
up prior to the start-up of normal construction activities.
 Ensure no materials are stored near edges/openings.
 Ensure no loose materials are left uncontrolled.
 All work at height to be suspended during high winds.
 Ensure that any scaffolds and mobile towers are adequately secured and tied.
 Ensure compound/site boundary fencing is securely erected in accordance with
manufacturer’s recommendations and any DM approvals.
 Ensure that barriers/signage are adequately secured.
 Ensure adequate arrangements are in place to secure any loose materials which may
become projectiles, whether at ground level and or at height.
 Remind personnel of their designated smoking areas and ensure that cigarettes are
properly put out to prevent it from igniting fires.
 Ensure a site inspection is undertaken before operatives are permitted to return to
work.
4.3 Sand Storms
Weatherforecastsare requiredtobe monitoredforthe likelihood of sandstorms. The HSE
departmentwill notifythe ProjectTeamin the case of any possibilitiesof sandstorm. The
Project Director/Manager must inititate to suspend all the external works and to remove
persons to safe areas as the dust levels could put health and safety at risk.
In case of minordustall operativesworkingexternal workswillbe providedsuitablekindof
face mask to avoid dust inhalation.
In eventof severe sandstormwhere visibilityfall below 10m, external workswill be called
off till stormsubside.Work will resume afterweatherconditions isback to normal and no
danger to any employees on project site.
Rest areas and eating areas to be suitably protected from sand ingress by closing any
openings and sealing the all joints and holes.
4.4 Heavy Rain & Floods
Although rainfall in the UAE is limited,we can experience up to 8 to 10 mm of rain in one
day which can cause occupational safety and health issues within the workplace. Rainfall

and resultant flood are becoming a common hazard in this country. The facilities/
construction site are not effectively suitable for such scenario since there is no proper
drainage system.
Considering the consequences after a rain, the following steps will be implemented as a
good practices to avoid damages and other indirect losses:
 All external industrial electrical plugs & sockets used will be weather proof.
 The stability of all excavations must be inspected following periods of rain
(additional inspection regime over and above the start of shift inspection must be
done as and when required).
 Use of Cranes, Mobile Elevating Work Platforms and Concrete Pumps during
periods of lightning must be prohibited.
 Worker welfare/rest facilities must be adequately protected from water ingress.
 All Electrical distribution boards must be IP rated and fitted with IP rated glands
to prevent water ingress.
 ELCB must be checked monthly and electrical cables routed off ground where
possible, else underground.
 Adequate provisions for dewatering of accumulated water will be considered.
 All drivers must be briefed on precautions to be taken while driving.
Electrical Distribution Boxes
EveryElectrical Distributionboxesare coveredwithPlywoodoverheadprotectionplacedon
scaffolding pipes. Moreover all DB’s are weather proof (IP rated) and doors are having
rubber sealant in between to prevent water droplets from infiltrating inside the DB. Also
everyDBis placedonstandswhichis1m from the ground.OneveryDB emergencycontact
number of the concerned electrcians are labelled with their photographs (including Night
Shift if applicable). These persons will be responsible in placing plastic cover/wrapper on
every DB, before rain as an additional protection.
Step Down Transformers (SDT)
All SDT will be placed on stands with overhead protection when used at site. As for DBs,
Electrical Assistance contact numbers with photographsare labelled on every stands who
will be responsible for providing plastic cover/wrapper before rain.
Temporary Roof / Tents / Shades

to avoid flooding.
Septic Tanks
Ensure that septic tanks are emptied periodically and covered properly at all time. Septic
tankswill be installedwithlimitswitchalarmsystemtoavoidoverflowing. Thiswillbe under
the direct supervison of the Store Keeper.
General
Upon hearing/ receiving the weather forecast reports (from Logistic dept) regarding the
expected heavy rain, following precautions must be implemented:
 All the external works must be suspended until the rain ceases.
 Ensure all materials stored at site are protected/ secured before rain commence
 Ensure all temporary electrical connections at site, computers and all other electrical
appliance inside the temporary offices are protected from water leakage.
 Remove plant and equipment from low lying area and park them in a safe location.
 Secure or remove materials which can be washed or damaged by flooding.
 Ensure power supply are shut off.
 Alert every personnel at site and if required evacuate them if there is any chance of
flooding.
Work can only resume whenit is safe and inspection carriedout by HSE team and Logistic
team along with the Construction Manager.
